Application: apper-sentinel (0.7.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Before the problem I had upgraded my system to openSUSE 12.1. After restarting the computer, I had messages of Apper trying to configure a proxy, but the box dialog was crashing on its own. Each time I try to refresh the list of packages and check for updates, a box dialog appears informing me about the error. That's it

- Unusual behavior I noticed:
Black boxes appear for some seconds on my screen and they dissappear afterwards

The crash can be reproduced every time.

-- Backtrace:
Application: Apper (apper-sentinel), signal: Segmentation fault
