[MonoDevelop] MD crashes when opening a file

[James Fitzsimons]

Hi all,

Finally got MD from SVN HEAD to build and run. Unfortunately it crashes
when I try to open a .cs file. It will happily open a project, but when
I expand the project tree and double click on a .cs file I get the
following error:

I also get loads of these errors immediately after starting MD:

(MonoDevelop:16979): GdkPixbuf-CRITICAL **: file gdk-pixbuf-scale.c:
line 246 (gdk_pixbuf_scale_simple): assertion `src != NULL' failed

Should I raise a bug against this?

Cheers,
James Fitzsimons
