Exact Message: There was a connection error: Network failure.

Steps to Reproduce: Connect; Disable network connection (e.g. remove the cable ^^ or just go to hibernate); Kopete needs to reconnect; Kopete shows above message; kopete crashes

I just tried to reproduce this bug. I could deactivate my wlan without kopete crashing. But hibernation for more than a few seconds (I was away for 1 hour)
made kopete crash. Here is the backtrace. Hope it helps.

Application: Kopete (kopete), signal SIGSEGV

May this be related to bug 176821 ?

I don't think so... my kopete version does not crash when I go offline manually.

I'm still having this issue. Also when I'm connected a long time (>10h):

This bug really annoys me, its happening daily here. What do you need to fix it? What can we do?

the same happens when kopete fails to connect gchat (~four times a day, and when recovering from hibernation... :S )

I can confirm this with the Kubuntu 4.2beta2  packages.

Backtrace:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

I couldn't reproduce this problem since the release of kde 4.2 I think. What about the others? May I close?

I think it is fixed in 4.2.0 release

Marking as WORKSFORME. Please re-open if anybody experience this crash again. Thanks
