Bug 306802

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.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I was trying to run the Python track at Codecademy.com, and the gui wasn't working in Firefox or Konquerer, so I wanted to install Chrome using Apper.

I started Apper from the KDE menu, selected Applications, selected Graphical Internet, and *boom*, Apper crashed and the Crash Reporting Assistant popped up.

Surprisingly, downloading the debugging symbols worked this time; that is to say, after downloading them all, the stack trace became three-star quality, which has not been my experience to date.

Good luck solving this.

-- Backtrace:
Application: Apper (apper), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
