           Summary: Kscreenshot while movie playing: many crashes,
                    duplicate instances of kscreenshot and lockup
           Product: kde
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: gabextreme at gmail.com


Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-02062903-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Tried to take a screenshot of a video that's playing in SMPlayer to demonstrate
video tearing for another bug I'm writing, but lo and behold, a crash. 

Video was playing (and tearing). I pressed Prt Sc. I waited and waited...but
nothing happened. Finally I exited the video and wam. I get 20+ screenshot apps
starting to load, and a crash message.
