Shortcuts control panel crashes Pencil

Shortcuts control panel crashes Pencil consistently when I try to backspace to clear a key binding:

segfault at 7fd34469e718 ip 00007fd34469e718 sp 00007fffde060308 error 15 in libc-2.17.so[7fd34469e000+2000]….segfault at 11e7fa0 ip 00000000011e7fa0 sp 00007fff61c02da8 error 15…and similar

@morevnaproject,
Could you do me a favor, try to reproduce this issue?
I'm wondering whether it happened on your machine or not.

Hi, @chchwy!
I choose keybinding, hit "Backspace" and appropriate text appears in the "Shortcuts" field. No crash happening.
QT 4.8.4 here, Fedora 18 x86_64.

Thank you, @morevnaproject.

When it specifically happens for me requires two presses of backspace. The first changes the shortcut to "Backspace" (i was thinking it would clear the shortcut) and the second knocks out the program.

Debian Sid 64-bit, Qt 4.8.5

EDIT: I believe when i originally posted this bug at the forums, i was using the more recent git source, and not the 0.5.3 "official" release, where the bug doesn't seem to occur (instead there is a box asking to overwrite "Backspace"). So i'm not sure if it applies in this particular bug list. In any case, i can still reproduce the crash in the current master

Hey, right. I can confirm - double press of Backspace crashes for me too.

I fixed the race condition in #84 . The whole keyboard shortcuts page deserves some work though.
