Application: kdeinit5 (15.12.1)

Qt Version: 5.6.0
Operating System: Linux 4.5.0-0.rc0.git8.1.fc24.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
After starting X the KDE desktop appeared. This took quite a while to happen. Two konsoles were automatically started with, I believe, 5 tabs each. They appeared at the desired location, from a previous manual save, but never appeared to complete init. There as no bash prompt. Tabs were NOT drawn. There were no menu items listed at the top of a "normal" konsole. I poked the big X at the far right hand side of the konsole widget and it went away. A minute later, this drkonki dialog appeared.

- Unusual behavior I noticed:

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Floating point exception
