I can reproduce this bug. It happens (at least) under macOS. But it does not freeze the application or the machine. @a_marhoon91’s screen shot is too small to read, so I am reproducing the error message I received. Hopefully, it will be more legible:
I’m having problem with PDF too, but i’m unable to made new topic in bug categories. Can i post the bug here?

Fixed in the latest version (19.1.20)
