[Evolution] Evo 2.2.1 always 'unexpectedly closed'

["LLLActive GMail com" <lllactive gmail com>]

Hi all,

I have Evo 2.2.1 Groupware Suite from Novell's Suse 9.3 Pro distro. It suddenly does not close properly. Error Message: "The Application "evolution-2.2" has quit unexpectedly"; " You can inform the developers of what happened to help them fix it. Or you can restart the application right now."
Bug Buddy also hangs up (complains that gnome is older than 6 months). Restart works but no clean shutdown. 'Send and Receive' also hangs with 'Waiting' for the pop servers. Where should I start looking. 

Otherwise all works with Evo., sometimes it also fetches mail from the pop servers.

Please take into consideration that I'm a novice with 6 months SuSE Linux experience, only as user and i'm no programmer. 

Greetings
Al
