Since I upgraded to 2.0.3 ardour segfaults if .ardour2 is not clean. This is the message it leaves behind: (ardour-2.0.3:11963): GLib-GObject-CRITICAL **: g_type_interface_peek: assertion `instance_class != NULL' failed Segmentation fault (core dumped) I have done some tests and I think it is because of something in ardour.rc, I will be happy to test any patch.

could you please follow http://www.gentoo.org/proj/en/qa/backtraces.xml to get a backtrace ? And perhaps also attach your ardour.rc, if you think it's the cause so that I can try to reproduce it.

weird, I don't get the problem here. Could you please paste the output of "bt full" ? getting the values of the different variables could help.
still working fine here, please reopen with more info
sorry for the late reply, I was on holidays :-) Anyway, I find that 2.0.5 seems to fix this for me, so I wouldn't know what to add. Thanks a lot for your support anyway!
