Kmail embedded in kontact: after started the new email check for an account, the check does not really terminate (literally "it stay on the email check"); after exiting kontact it does not really quit, not allowing it to be restarted.

PS: please report bugs in English.

Comment 2 Jan-Willem van de Meent 2010-11-11 12:24:32 UTC

I am experiencing this bug as well. If kontact is exited while an e-mail check (cached imap) is in progress, the window is closed but the kontact process does not terminate and needs to be killed manually.

This behaviour is in itself annoying enough -- since most users may not realise the reason why kontact fails to restart. What is worse is that the imap cache occasionally seems to get corrupted. Every month or so I need to re-download my 1 GB archive from gmail, which takes a long time.

Since the kdepim 4.5 release still seems some time off, is there any chance of getting a fix for this on a point release?
