File not found: transaction 'ct', path 'trunk/Setup'

Hello,

Once in a while we're getting the following error when updating our local copy. Usually I can do the update again however it happened to us quite a few times that we've had to delete our local directory tree and check out again. What could be causing this? When it happens, what I can do to fix it? It seems to happen if I commit individual files instead of doing my commit on the trunk directory however I'm 100% sure about this.
