I've never noticed this test failure before...

Comment 1 John Arthorne CLA 2011-10-28 14:55:06 EDT 
It looks to me like this test is vulnerable to a background snapshot operation happening. It basically does the following:

1) register save participant
2) assert saved tree is non-null
3) perform a snapshot
4) assert saved tree is null

However if a background snapshot started by a previous test caused 3) to happen before 2), the test would fail.

Szymon does anyone on your team run on Mac?

I have a Mac on my desk. It failed again in N20111028-2000, but is fine in N20111029-2000. I'll check locally on my Mac.

Does not fail locally and recent builds look fine too.

I could not reproduce the problem locally and builds still look fine. Marking this WORKSFORME. Feel free to reopen, if you find steps or it starts failing again.
