Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.2-300.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
Log on to Fedora22, open browser window or any other window.

- Unusual behavior I noticed:
Plasma crashed. When it automatically restarts, scroll wheel no longer works in browser.
Also, after first crash, it restarts and crashes several times.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
