           Summary: kmail crashes when /home remains out of disk space
           Product: kontact
           Version: 4.4.3
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mihai.dontu at gmail.com


Application: kontact (4.4.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-tuxonice x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I was building a project which managed to take all the free disk space from
/home. After a few seconds (or 5min max. - I think it depends on when KMail
checks for mail), KMail started using 100% of my CPU and after another couple
of seconds it got into disksleep and xfssyncd started taking all the CPU (I use
XFS). I waited a bit and deleted a large directory I didn't use anymore,
freeing ~160MB. That's when KMail crashed.

The crash can be reproduced every time.
