Application: plasmashell ()

Qt Version: 5.4.0
Operating System: Linux 3.18.5-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to figure out how to run Thunderbird with the FireTray addon. Using the addon freezes Thunderbird since Plasma 5, i.e. if you close/Alt+F4 the application, it dies. Also, if you launch the app from the terminal (I was trying to get some debug output) and not from a keybind or the launcher, it doesn't freeze, but it also behaves weird, which led in the end to plasmashell crash.

- Custom settings of the application:
Using FireTray 0.5.4 on Thunderbird.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
