Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31custom1 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
In KPackagekit I was searching some packages. I typed "capi" in search field.
It found 3 packages. When I clicked at "wine-capi" on packages list, application unexpectedly crashed.

Does this happens all the time?
Also this bug seems to break at kdelibs level,
I just can't reproduce it.

Another one-off occurrence with KPK 0.4.2, KDE 4.3.1 and Qt 4.5.2 here:

Unfortunately neither of the backtraces we have are really sufficient
for debugging, as this seems to be a KExtendableItemDelegate bug :(
