Application: apper (0.7.2)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.2
Operating System: Linux 3.5.3-1.fc17.i686 i686
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
I was prompted to update by the task bar (5 updates).  The app seemed to finish.  I clicked on "Check for updates."  It said something to the effect "Waiting for Processes to finish."  I gave it about 10 minutes... still nothing.  I finally clicked on 'X' in the upper left hand corner, and it crashed.  I had just installed the @kde-desktop package to check out the KDE desktop.  I'm running Fedora 17 with the default Gnome3 desktop.

-- Backtrace:
Application: Apper (apper), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
