           Summary: kwin suddenly crashes, signal SIGSEGV
           Product: kwin
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kwin@kde.org
        ReportedBy: avoulk@gmail.com


Version:            (using KDE 4.1.0)
Compiler:          4.3.1 
OS:                Linux
Installed from:    Unlisted Binary Package

With no obvious reason, kwin crashes, with signal SIGSEGV. I am not sure if
this is a konqueror side-effect, as the crash does not always appear when
having konqueror open.. I am using Archlinux (i686), and the usual backtrace is
the following:

I've searched for a while in the bugzilla, and found no obvious resemblance to
another bug, so i am posting it.

Thank you for your hard work!
