Crash report

[apet2929]

I was modifying the output directory (i didnt want to output to the default directory), I pressed backspace and it crashed. I did not have any files in the pack yet, this was the only thing I had done on the pack. This has happened multiple times, with and without images in the pack.

Sorry for the late replay.

I believe that the same old bug that was fixed in #98
Please feel free to reopen if you think the crash is about something else.
