Application: kpackagekit (0.5.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-174.2.22.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was attempting to use KPackageKit to install several packages after a fresh install of Fedora 12 KDE. I typed in my search text and started the search, then decided to narrow the search using the category combobox. The program then segfaulted after trying to change the category. Maybe caused by initializing a search when one is in progress?

The crash can be reproduced some of the time.

 -- Backtrace:
