Something universal about pretty much all software is the fact that it occasionally crashes. The nice thing about open source software is that you can actually do something about it even if you’re not a programmer yourself. You can generate a so-called backtrace, with which you can help developers figure out why their program is crashing.
The following video tutorial demonstrates a crash with Darktable but the tutorial should be applicable to most applications. And don’t worry the crash in the video got fixed minutes after I made the video.
