Bug 122055

Version:            (using KDE KDE 3.5.1)
Installed from:    Ubuntu Packages

KMail's job status list had one entry "Fetching mail xxx.." for a long time (on an IMAP account).

I've clicked "cancel" to abort it and an "Error - KMail" disalog popped up, but has not been finished getting drawed. This is probably the "Connection to xxx is broken" message that I've seen before when canceling a job.

Now there seems to be a deadlock situation between some components, as KMail eats up all CPU and the whole application windows does not get redrawn.

When I move the half-painted error dialog, "ghost images" of it stay in the preview pane, but folder and messages list stay white all the time.

There's also the job status bar popup (which displays the currently active tasks) which stays plain grey without any text when moving the error popup dialog window over it.
