Bug 251777

Application: kmix (3.6)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Setting the VolumeDown shortcut to win-D produced resulted in a box showing "[][][][][]" where all symbols were boxes and some were superscript. That is, the shortcut setter thought I was pressing the key "[][][][][]". Setting VolumeUp to win-F produces the same box. I can only assume that "[][][][][]" is synonymous with the win key. This is what xev outputs:

KeyRelease event, serial 33, synthetic NO, window 0x2600001,
    root 0x1ad, subw 0x0, time 12854160, (145,1), root:(1801,24),
    state 0x40, keycode 133 (keysym 0xffeb, Super_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

After doing this twice, kmix always crashes.

The crash can be reproduced every time.

 -- Backtrace:
