Quick update:

The crash still happens with the current dev branch. On the upside, it has a 
test case now and is prioritized "critical" for 5.1, so from a bureaucratic 
point of view, it will hopefully get fixed. (I've looked at the patch 
introducing it, but didn't get very far -- it's a 3000+ LOC monster which 
optimizes all kinds of aspects in qquicktextedit.cpp. It's also not easily 
reversible on top of dev's HEAD. For now, I've disabled our usage of TextArea 
in the plasma2 test code, which let's it at least not crash. Will be re-
enabled once the Qt bug is fixed -- I'll keep an eye on that.

Cheers,
