bzr hangs when trying to pull an uploaded branch

[Wade Williams]

This may be an invalid operation, but bzr should return an error message rather than hang.

To reproduce:

bzr init test
cd test
echo "first change" > a
bzr add
bzr ci -m "initial import"
bzr push sftp:<some url>

bzr pull sftp:<same url as above>
bzr will just hang at this point. As I said, this is probably an invalid operation, but bzr should return an error rather than just hang.

This should work; can you hit ctrl-\ to get a debugger to open and type
bt\n
to get a backtrace?

Thanks,
Rob

After more investigation, I believe this bug is the same thing as 484558 and can probably be closed in favor of the other one.
