Application: rekonq (2.3.2)
KDE Platform Version: 4.11.1
Qt Version: 4.8.5
Operating System: Linux 3.11.1-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

-- Information about the crash:
- What I was doing when the application crashed:
I was playing Grooveshark music, when the screensaver started. 
The screensaver uses music also, so maybe something to do with simultanious use of the sound drivers, maybe something with flash. 
I'm not sure what plugin Rekonq uses; I've got both Adobe Flash and Gnash on the system.

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