I couldn't reproduce this here: the Git GUI didn't pop up for me.
Perhaps something is missing from the recipe ("C-x g" was also
unbound), or maybe it's because my Git is configured to be run only
from Git Bash, not from anywhere else on Windows.

However, I installed a change which might fix this problem.  Please
test the current master.  Also, just so I'm sure I didn't miss
anything, please post the backtrace from all the threads ("thread
apply all bt" at GDB prompt), from the binary where you get these
aborts.

Thanks.
