I can't get it reproduced in 4.7.3,on fedora 16 instead I get a nice switch from activities to widgets and v.v. Is it still there?
Will, any news on this?

Still here apparently.
I can't understand how can this possibly happen. Say you have your Activity Manager open, how can it still be open when you try to add a widget? The Activity Manager is set to hide when any mouse action happens outside its area. Plus, this is marked as a regression but I don't see any report of it in 4.8.90 and I can't reproduce. If there's any additional info, please add it here.

The fact that there are two full backtraces seems to hint towards this being a real crash – no matter how it is triggered. > Plus, this is marked as a regression but I don't see any report of it in > 4.8.90 and I can't reproduce. If there's any additional info, please add it > here. Probably because this was filed against 4.7 but nobody cared about it. It was/is a regression compared to versions before the one reported. Regarding "no report against 4.9 betas". Probably because compared to 4.8 and 4.7 nobody uses 4.9 yet, i.e. it seems obvious that the probability of somebody triggering this bug relates to the amount of users of a given KDE version.

It is still in Kubuntu Saucy (KDE 4.11.2) with Opening Activity Manager and then click on "add widget". sometimes it takes a second, but then it crashed.
