           Summary: First search became weird, then kmail went down
           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: shai at platonix.com


Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I have a folder where I dump several mailing lists, and a search to extract one
of them. I knew that this search found 26 unread messages out of ~200. Today I
glanced at it, and it only showed one unread, and claimed to have only two in
total. I tried to look at its details to investigate, and KMail crashed.
