Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I had clicked on the KLauncher application menu, started typing 'KRDC' and Plasma crashed after typing I misstyped 'KVP [backspace][backspace]'.

Similar to 354511 I think, but I couldn't figure out how to have KDE Crash Reporter connect these two reports.

Thanks for KDE!

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
