That did help (I think I still have an unrelated leak). I think a few
things could be made more clear in the docs (I'm not 100% sure I'm correct
either):

-A newly created source (from g_idle_source_new() ) has a reference count
of 1 not 0.

-g_source_attach() increases the reference count by 1

-returning FALSE in a source callback function detaches the source from
the source's attached main context, and decreases the reference count by 1

-Once a source has been detached by source callback function returning
FALSE, it can not be reattached g_source_attach(). An assertion error is
thrown. You can however, decrease the source's reference count down to 0 so
it will free itself, then create a fresh source.
