           Summary: Crash if pressing answer when no mail is selected
           Product: kmail
           Version: 1.11.2
          Platform: Debian testing
        OS/Version: unspecified
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: schwarzerf at gmail.com


Version:           1.11.2 (using KDE 4.2.2)
Installed from:    Debian testing/unstable Packages

Sometimes if I remove a thread (Ctrl+Del) no mail is selected afterwards. If I
then press Reply, KMail crashes with the following backtrace. The case is
cleanly reproducable here.
