Trunk doesn't crash as easily in gdb. I suppose you fixed the issue
with the graphical frontend. Thanks a lot!

Whether that issue was the one I used for this threads Subject I'm unsure of.

Jan, what about the other crash I had posted a full backtrace of when I tried
it in a terminal?
It crashes when I do the same, but use C-g to cancel the visual selection
iniated via evil-mode in progress.

gdb ...

(gdb) run -nw

press v, do some selection, press C-g
