           Product: kmail
           Version: 1.10.0
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: Regnaron web de


Version:           1.10.0 (using 4.1.00 (KDE 4.1.0), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc

All of a sudden (I did not even know that I had kmail open any longer) I recieved a not that kmail crashed. Several minutes before I had clicked on a mailto link which brought up kmail. However, I closed that window. So maybe due to that kmail was still running in the background somehow. Anyway, my backtrace is:
