The buildbot hit a test failure in tubes/test-get-available-tubes.py, because the NewChannels signal it caught only had one channel in it, not two. This turns out to be the test catching a bug in Gabble sometimes (it's a really hard race to win). Gabble announces the Channel.Type.Tubes channel twice: once immediately after you request it, and again when we get presences etc.
Here is a branch which adds a test for this bug. It is misnamed because I thought the test was buggy, not Gabble. http://git.collabora.co.uk/?p=user/wjt/telepathy-gabble-wjt.git;a=shortlog;h=refs/heads/fix-test-get-available-tubes
This branch doesn't exist anymore, and Tubes channels are disappearing now anyway, so I'm going to close this.
