19:55:13 <daf> smcv: any idea on http://paste.debian.net/53691/ ?
19:58:33 <smcv> daf: I think telepathy-glib/properties-mixin.c line 
433 leaks the GValue itself
19:58:58 <smcv> daf: (but not its contents!)
19:59:12 <daf> smcv: want me to file a bug?
19:59:23 <daf> or do you want to instafix it?
20:00:11 <smcv> daf: please, with a tested patch (which I think is to g_free it as well, or use g_boxed_free (G_TYPE_VALUE, prop_val))
20:00:32 <smcv> daf: check with lcov that the offending code was executed without crashing
20:01:01 <smcv> daf: I *think* the GValue boxed type is defined as being g_malloc'd but I can't be sure

Further comments:

20:28:18 <      daf> smcv: hm
20:28:36 <      daf> smcv: I guess I'd need to build an lcov-enabled tp-glib
                     and then run the Gabble test suite against it
20:29:44 <      daf> smcv: I don't understand this code though
20:30:21 <      daf> smcv: the GValue gets stashed in the conctext on line
                     442, but it's immediately followed by things that return
                     errors
