BUG: Crash after opening a project with out language support

I'm a fairly experienced programmer (13 years) with good C++ but only little
KDE knowledge.
I would like to contribute to your very cool project, so I download the
sources from CVS HEAD
today and played around a little.

And now comes my first contribution to gideon... :)

When you open a project where the language support is missing (in my case
the java support wasn't compiled),
then gideon crashes in the ClassViewPart, because the method setupPopup()
tries to query the features of
the language

ClassViewPart.cpp, line 79:
   KDevLanguageSupport::Features features = languageSupport()->features();

IMHO the best fix would be not to load the project at all...

core.cpp, line 543:
   } else {
      KMessageBox::sorry(win, i18n("No language plugin for %1

Next time, I'll know how to post a  patch. :)
