Monodevelop used to crash on my system after typing a few letters with this message: (MonoDevelop:29817): Gtk-WARNING **: Invalid text buffer iterator: either the iterator is uninitialized, or the characters/pixbufs/widgets in the buffer have been modified since the iterator was created. You must use marks, character numbers, or line numbers to preserve a position across buffer modifications. You can apply tags and insert marks without invalidating your iterators, but any mutation that affects 'indexable' buffer contents (contents that can be referred to by character offset) will invalidate all outstanding iterators /usr/bin/monodevelop: line 40: 29817 Speicherzugriffsfehler mono --debug ./MonoDevelop.exe $@ I didn't file a bug report because I installed some things from CVS and thought it was a problem with my installation in here. Now yesterday I upgraded my gnome desktop to ~x86 2.6 version which includes GTK+ 2.4 and now monodevelop works like a charm. It's only a guess, but could it be that monodevelop depends on GTK+ 2.4?

This should be fine for gtk+-2.2... MD doesn't really bind anything particular to gtk+-2.2. Is this bug still valid with the new Beta2 mono stuff just added to portage?
Sorry I didn't keep this bugreport up to date. It seems to have been a bug in monodevelop not related to GTK+ - at least Todd Bermann says so. With the latest MonoDevelop everything works fine.
