Bug 280904

Application: konversation (1.3.1)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

-- Information about the crash:
It seems Konvi is not fit yet for use with KDE Activities.

- What I was doing when the application crashed:

1) launch Konversation
2) assign Konversation to more then one activity (e.g. "Everyday" and "Coding")
3) close one activity (e.g. "Coding")

* at this stage Konvi's conversation/main panel goes blank

4) select a different tab then is selected at the moment

* at this stage Konversation crashes

I replicated this already a few times and it crashed every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
