I didn't check carrefully but reading the code it seems that tp_account_set_enabled_async leaks the GSimpleAsyncResult. It should be unrefed after g_simple_async_result_complete_in_idle. We should probably audit the code as that's a common pattern.
Shouldn't be too difficult for a new contributor who's familiar with GObject idioms?
This bug is sufficiently low-hanging that we should fix it before 0.12, so I've claimed it.

Fixed in git for 0.11.15, which is imminent
