Version: (using KDE 4.2.90) OS: Linux Installed from: Ubuntu Packages When i click on lancelot menu and kopete is open (can by only in tray). All panel became frozen and i must restart plasma-desktop or close kopete, then everything works good to time when i do this again. I'm not sure but i thing that lancelot is broken after last upgrade, befor (after upgrade to beta2 on kubuntu (this broken update without all packages) before upgrade lancelot) everything works great.
Please try whether it is sufficient just to call 'killall lancelot' to unlock plasma.
Can you reproduce it always (after log-out / log-in)? (since "It works for me TM")
Ok, as i observe problem exists when i have error in kopete (when kopete can't connect to skype). It's probably kopete problem, but not only:)
Same kind of problem here. After a few hours running (7 or 8hrs), lancelot began freezing plasma-desktop. After approx. 20s I get a white rectangle (instead of the menu) that stays on top of other windows. If I close kopete, it still happens after a killall lancelot and a plasma-desktop restart... Maybe this is related to #196809 ?
