Do you have any experience debugging with GDB? If not, I can write a step by step
guide. Anyway, you will need GDB installed, and also a gpick version with debug
information (attached)

I have no experience with debugging on linux whatsoever.

After you have installed GDB and gpick with debugging information, start gpick like this:
gdb gpick | tee gpick-debug.log

This will write GDB output to terminal screen and 'gpick-debug.log' file, which you
should later attach to this issue.

After you run the above command you should get something like this:
Temporary breakpoint 1, main (argc=1, argv=0x7fffffffe8d8)
at source/main.cpp:838
(gdb)

Now type 'c' or 'continue' (without quotes) and press enter

Now if the output has 'Segmentation fault' at the end of the first line, type
'backtrace' (without quotes), otherwise type 'c' or 'continue' again

Lastly type 'quit' to close GDB, and post the 'gpick-debug.log' file here

After I run that gdb command, I get this:

Good, I will release a new version with this fix in an hour or so. Thanks for taking
