Application: apper-sentinel (0.7.1)
KDE Platform Version: 4.9.4
Qt Version: 4.8.2
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Installing a new package, then pressing close, the crash happened after that.

Note that the report that this is possibly related to is marked closed with a much older version of KDE- since this is a much later version, either the bug wasn't fully solved, or it is another problem. Several of the duplicates do look very similar to this one.

-- Backtrace:
Application: Apper (apper-sentinel), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
