Hi folks, I have already posted this matter in the gtk-sharp mailing list, but the guys there suspect my issue to be related to the MonoDevelop RPM I am using: I am using gtk-sharp2 incl. glib-sharp2-2.12.10-85.13.x86_64 for my Mono project and for MonoDevelop (5.0.1-110.14) itself. The issue is that after the recent update, MD crashes a few seconds after opening whatever project. I get the following error message: monodevelop: symbol lookup error: /usr/lib64/libglibsharpglue-2.so: undefined symbol: g_type_check_instance_is_fundamentally_a The version of glib-sharp2 is the most recent I can get for my openSuSE 12.3 machine. For MD and the Mono files incl. gtk-sharp2 I am using Mono/Factory as a repo. One of the gtk-sharp guys told me the instance checking routine in libglibsharpglue had been added in May 2014: https://mail.gnome.org/archives/commits-list/2014-May/msg08836.html What shall I do? Thank you for any useful hints.
