           Summary: Kmail crashed when changing text position
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: seajey.serg at gmail.com


Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.2
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Accidentally I removed my .kde folder so I have to configure my applications
anew.
After perfoming  Antispam wizard  two icons appeared on toolbar - to classify
message as SPAM or Good one.
But a could not change there icons so I've delete two entries:
toolbar_filter_actions and toolbar_messagetag_actions and adding configurable
filters kmail began to eat all available memory and CPU. After manually killing
kmail and restarting it there is no icons of "Classify as spam" and "Classify
as not spam" filters in toolbar though they are added to list.

After changing text position to text under icons or adding this filters to
toolbar kmail crashes.
