bizarre multiscreen crash

Thu May 20 09:59:44 CEST 2010

so I was trying to ensure views are always created when new screens appear... 
technically that was a success - but directly after creation I get this 
bizarre crash from the systray. it's happening very soon after 
PlasmaApp::createWaitingDesktops() returns, and *always* happens when a new 
desktopview is created in response to a new screen. creating views on plasma 
startup still works fine.

I didn't have this problem last week, though. o.0 I'm confused and very tired, 
so I'm attaching it here and hoping magical fairies will have fixed it in the 
morning ;)

oh, but the good news is - other than not always creating views, activities 
and multiscreen and per-desktop-views should all get along nicely now :) if 
you look at http://techbase.kde.org/Projects/Plasma/ZUI you'll see that 
although there's still work to be done, most of the critical things are fixed! 
:) :) me and aaron and ivan have been chipping away at the code... hmm, I 
guess this means it's time for a screencast.
