Bug Report: Click+Drag on Linux crashes program (always)

lightnb · April 22, 2020, 4:18am

Steps to reproduce:

Open on Linux, click something, like the button that turns help on and off. Or in a blank area of the window. While holding the left mouse, drag the mouse. The program crashes. Always reproducible.

Output in terminal:

What edition (desktop, server, cloud)? What version number?

lightnb · April 22, 2020, 2:08pm

Desktop edition, software version 20.2.83 (that’s the number at the bottom of the help tab, I assume it’s a version), on Mint 19.3 with Mate (Ubuntu). I downloaded the latest appimage last night.

Tut · April 22, 2020, 2:46pm

I have put this into the bugs category. It would help if you post a screen shot of any error message thrown by the program itself.

If it’s any help, I can confirm this, and here it the log I have:

This is on arch linux and I am using:

That is the latest version available in the repo.

Tut · June 14, 2020, 5:18pm

@lightnb and @novica , there have been hundreds of updates since you first reported this problem. Does it still happen? Or has it possibly been resolved by changes to the program?

novica · June 14, 2020, 5:37pm

I tested on arch linux and as far as i can see there aren’t any new packages there, so no way for me to verify.

Tut · June 14, 2020, 5:43pm

@novica, my question was not related to new packages for arch linux. (But maybe I am misunderstanding what you mean by “there aren’t any new packages there.”

In post #5 above, you stated you could reproduce the problem of a crash when clicking and dragging. My question is whether that still happens to you with a current version of Manager. I was not thinking about versions of linux. In other words, doing exactly what you did before, does a current version of Manager still crash?

Can anyone else using Linux reproduce this problem of crashing when clicking and dragging? If so, what version of Manager are you using?

novica · June 14, 2020, 5:59pm

Tut, yes, I can reproduce the problem on Arch Linux which is what I am using. But since the package maintainer for Manager for Arch Linux hasn’t published a new package I cannot use the newest version and can’t check if the bug is still there.

Tut · June 14, 2020, 8:11pm

Ah, now I understand. Thank you.

@Tut - hope this helps.

Hello! New user here on Linux non-server edition.

Yes, “drag crash” is reliably reproducible whenever a mouse drag is initiated.
This occurs when inadvertently selecting text anywhere on the interface then dragging it.
It also occurs in Chart of Accounts when attempting to re-order Accounts (by dragging the double-arrow symbol).
The symptom is an instant crash with no delay nor message.

I will append Inxi output showing I am running Kubuntu, being KDE on Ubuntu 20.04 LTS ie. the latest.
Running the latest AppImage v 20.7.97 (20th July). Also happened on other versions over the last few weeks.

I have not noticed any data corruption despite many crashes (thank god!).

I hope someone can pass this info on to the developer as it is not giving my customer confidence in the new software I just installed for them

Despite this problem, I am overall rather pleased with Manager and am thankful that the software is available on all platforms and is affordable for all sizes of business, in this case a small farm using it for Receipt/Payments/BAS only.

That happens automatically when a topic goes into the bugs category. In this case, the developer is the one who put it there.

This is still reproducible. Just try reordering account in chart of accounts.

That is why the topic is still in the bugs category.

shah_p_r · September 12, 2020, 6:13pm

Any plan for fix? It is blocking reordering of account functionality.
Or is there a workaround?

lubos · September 12, 2020, 11:11pm

@shah_p_r I didn’t realize re-ordering function was actually being blocked by this bug.

This bug is present in third-party library. I’ve notified the developer and they fixed it in the latest version of their library but I can’t upgrade to it yet.

I will be looking into upgrading to fixed version of the library before end of this month.

novica · September 13, 2020, 7:31pm

I can still reproduce the bug, but have no issues with the reordering function.

Tut · September 13, 2020, 8:34pm

How do you reorder if clicking and dragging crashes the program? Reordering is a click-and-drag process now.
