Possible bug in ostree_repo_pull

[Vivek Dasmohapatra <vivek collabora co uk>]

While working on some code that needed to run a pull operation in a thread
(as per g_task_run_in_thread) I think I found a bug:

http://cgit.collabora.com/git/user/vivek/ostree.git/commit/?h=main-context-unbalanced-unref&id=17735ff9789afb77e80e11217cb81d226062e3f5

The GMainContext reffing/unreffing appears to be unbalanced to me.

Should I open a bug? Or is this trivial enough to import directly?
