Travis recorded a failure in test_util.FileUtil.test_disk_stats, while running under python2.6, against my "2023-caution" branch (git revision 1a07dfdedef4747784ad1798542a2f4c0b9c4be3). I can't think of any reason that ought to behave differently than the trunk revision 6a38a3c54e0846dea625f5af0a4d365f9368acf6 .

This test didn't fail for me on OS-X under python2.6 .

Also, the same code didn't fail under py2.6 (on travis). A rebased version of the same changes (where the rebasing only changed welcome.xhtml) passed on both 2.6 and 2.7 on travis. So I'm pretty sure this is intermittent. I ran test_util.FileUtil locally (OS-X py2.7) 4400 times without a failure.

I've pushed a branch with some extra debug prints to try and figure out what's going on.

(https://travis-ci.org/tahoe-lafs/tahoe-lafs/jobs/35096649) is a build which failed (finally).
