The top four patches of <http://git.collabora.co.uk/?p=user/smcv/telepathy-gabble-smcv.git;a=shortlog;h=refs/heads/08-privates> improve on our use of priv pointers.
The oldest is a bug waiting to happen, which bit me while working on Bug #13157; I think at least this one should be merged in 0.8, since it makes our conventional style for priv pointers compile correctly, but then crash when used.
The second-oldest removes an uninitialized, unused priv pointer from GabbleConnectionManager. GabbleConnectionManagerPrivate is never defined, so this pointer, while useless, can't be dereferenced, and the patch is hence less important. Up to reviewers whether this is a candidate for 0.8.
The two newest are arguable; I think we should at least have them in 0.9, but probably not 0.8.
Eh, it's fine. Merged to 0.8. and master; will be in 0.8.9 and 0.9.3.
