Config: notify_remove makes notifications cause segfaults

[Michal Hruby]

Notifications aren't removed properly after call to config_client_notify_remove, and adding notifications for the same keys with different data results in calling the notification multiple times. (hopefully this isn't bug in the python binding)

I've been working on debugging this for at least a week. This affects both the gconf and keyfile implementations (I haven't tested the memory backend yet, although I imagine that it affects that one too). Any help fixing this is appreciated.

Also, for future reference (from the bug reporting guidelines):

I think I fixed this in revision 242 of trunk.

Indeed it was fixed in 242, and the multi-notification issue in 244.
