Bug 286092

Application: konversation (1.3.1)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I use a proxy to connect to the internet and it disconnects after some time. Everytime it disconnects, i reconnect it, by loggin into the web-client. The internet works but the Konversation channels have been disconnected anyway. Now i refresh my already open channels in Konversation( from their server, not individually ). At this point the Konversation crashes. 
I think as far as Konversation is concerned, it would crash everytime the internet gets disconnected and i reconnect those channels after connecting to the internet again. I am little sure about this because this is what happened once, when I used a connection without proxy.
The bug that I think is related to this one, I have pointed out
- I hope this information was useful

The crash can be reproduced every time.
