This bug needs patching of either ruby-art or ruby-libglade. Since ruby-art is no longer maintained, so somebody could try to file a bug report against ruby-libglade. One way to fix the problem is by inserting the following at line 103 in libglade2.rb (at the start of the "guard_source_from_gc" method):

return if source == nil

But I have no way of knowing whether this will have any unwanted side effects or whether it may be a good idea to check it for nil."
