trying to init completion on a null class name
Before revision 200 it would crahs your application. I made that a qDebug to see how much my "fix" holds up in the real world. Happy it does.

On your setup it failed to load some tree classes, since your project contains some features not supported by the qmake parser. We should discuss about the handling of this issue.

That said, you tested trunk, which is still been developed (did you see that there is no option to disable the white space markings...? I am still evaluating this feature).

Can you edit your previous message and put numbers instead of bullets?
