After my system was just much to stable and old-fashioned the last week, I updated from Ubuntu Breezy to Dapper and successfully broke some things like dvb-t.
Anyway, I feel much more up-to-date now and I found some new issues with gtk-2.9.1 in anjuta. This version seems to be more strict in some cases which caused at least two new crashers. But to be fair I have to say that these were not GTK+ faults but bugs in anjuta which somehow worked with older versions.
Tommorow is the last day before X-mas in university. I think I will have to learn a lot in the short holidays :-|
