--- Comment #3 from Francis Herne <francis.he...@yahoo.co.uk> ---
It crashes intermittently with those flags (or all the Qt::QueuedConnection
flags around there) removed, but not every time as before.
I'm a bit busy actually using KDevelop to poke inside it much, maybe later this
week.
Backtrace looks different again...
