Description Shrikant Khare 2008-07-03 23:43:26 UTC
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:

Comment 1 Chani 2008-07-05 21:38:19 UTC
it seems that it's possible to remove activities while they're in use now.
when I added the remove-activity action, I only enabled it for ones that are *not* active, because it's not safe to remove active ones.

either it needs to go back to only allowing the user to remove inactive ones, or it needs to be made safe (perhaps by switching to the next activity or creating a new one if none are available).
