Python constants such as TelepathyGLib.HANDLE_TYPE_CONTACT or TelepathyGLib.PROP_CHANNEL_CHANNEL_TYPE don't work anymore.
I suspect all the constants are not exported any more.
Oh, actually TelepathyGLib.HANDLE_TYPE_CONTACT is now TelepathyGLib.HandleType.CONTACT but the PROP seems still missing.
Here is a fix http://git.collabora.co.uk/?p=user/cassidy/telepathy-glib;a=shortlog;h=refs/heads/gir-iface-32465
Merged to master for 0.13.10.
