Looms blows up badly when the tree nick does not exist in the loom.

"NoSuchThread" when trying to run regular commands on a loom.

This can be caused when an older loom was used, and the 'bzr nick' command executed to set the branch nick. Because the branch nick indexes into the loom, it has to always match up, and older bzr-loom versions did not ensure that this happened.

To fix it, open up .bzr/branch/branch.conf in an editor and set the nickname to the name of one of your threads.
