The source window crashes when displaying inline code after a (so far)
undetermined amount of time displaying G_OBJECT_IS_OBJECT assertion failures.
So far I've been able to figure out that this is due to a double free of
org.gnu.gdk.Window in Java-gnome, but cannot tell exactly why this is happening.
Also the windows that are causing the errors seems to be coming from the blocks
in inlined code, and not the parent SourceViewWidget
Java-gnome bug 324298 has been created to reflect this
This is now fixed in upstream java-gnome
