duchain seems to be broken

[Andreas Pakulat]

Hi,

somehow the duchain seems to be broken, opening a .cpp file in KDevelop
asserts in kateviewinternal:3180. According to Christoph Cullman its
probably wrong locking and indeed the assert checks that isSmartLocked()
is set.

Could somebody with some more knowledge about this please fix this?
