Application: kate (3.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.5-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:
I killed one instance of kate


- Unusual behavior I noticed:

1) There were two instances of kate running. One I started manually and one I started from Kontact using Open-With:

$ ps aux | grep kate
USER 14451  5.5  1.3 2782268 83668 ?       Sl   21:27   0:38 /usr/bin/kate /tmp/.private/XXX/kontactaC2743.index.3/THE_FILE
USER 21557  0.0  0.3 293064 20720 ?        S    21:35   0:00 /usr/bin/kate -b /tmp/.private/XXX/kontactaC2743.index.3/THE_FILE

No idea, why they both have the same file in their arguments.

2) Despite there being two kate processes, only one window was visible

3) The visible kate window hung after I pressed ^S. There was no significant disk activity, but the window never came back to life, even after almost a minute. Thus I killed this instance of kate using ctrl+alt+esc and clicking the window.
