Application that crashed: kontact
Version of the application: 4.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-3-686-bigmem i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
After 1 or 2 hours kmail gives the following error message:
"The connection to the server was unexpectedly closed or timed out. It will be re-established automatically if possible."
and then kmail crashes. It shows the same behavior on my laptop and both only related to the disconnected imap account.

I assume it's a duplicate of Bug 191589, which should be fixed in KDE 4.4. Since I'm relatively new to bug reporting, I wonder is it any use to report this one or am I only generating extra work?
