Comment 3 for bug 768784

I have found a workaround: branching from the repository without the use of the colo extension for the source works just fine, for example the following sequence of commands works just fine (output omitted for clarity):

$ bzr colo-init alltray
$ cd alltray
$ bzr branch bzr+ssh://aloe.trausch.us/home/mbt/Projects/desktop/alltray/.bzr/branches/origin/trunk colo:origin/trunk

Also, the following single command works in the same way:

$ bzr colo-fetch bzr+ssh://aloe.trausch.us/home/mbt/Projects/desktop/alltray/.bzr/branches/origin/trunk alltray

The only problem comes when using the colo: specifier to branch from the source on the remote system, such as:

$ bzr colo-fetch colo:bzr+ssh://aloe.trausch.us/home/mbt/Projects/desktop/alltray:origin/trunk alltray

This is the output that is placed in ~/.bzr.log for the execution of the previous command:
