           Summary: plasma crashed when removing activity
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: shrikantkhare gmail com


Version:            (using Devel)
Installed from:    Compiled sources
Compiler:          gcc (SUSE Linux) 4.3.1 20080507 openSUSE 11.0 gcc-4_3-branch revision 135036] 
OS:                Linux

Compiled kde 4.1 from svn trunk (rev:827748) on openSUSE 11.0 x86_64 installation.

Well, I was trying out the Activity feature of plasma and created 3 new Activites. Then, I could not find a way to delete the created activities. Finally, searched for and found the Plasma 4.1 FAQ. Now, I could not find the remove current desktop option in the right-click menu. It appears and disappears at random (should I report another bug??......using ctrl-shift-R ATM). Anyway I deleted the activity and plasma crashed. I have tried it again after logging and now, nothing seems to happen (neither plasma crashes nor the activity gets deleted). 

Here is the backtrace:

Application: Plasma Workspace (plasma), signal SIGSEGV
