Hi All,

Eli suggested I provide some additional info from my bzr.log after a
pull request with the Dhpss switch. I've included it below.

To ensure some clarity, a quick summary

- The failure happens very quickly i.e. within a minute or so of
issuing the command
- I have no problems accessing bzr repositories on other hosts, such
as launchpad.net
- I also got the same error when trying to access other bzr
repositories on savannah
- I can access the git repository on savannah with no problems
- I only see this error on my work system, which has a fast internet
connection.
- I have been accessing the bzr repository without problems before
last week for the last couple of years (since no long after the move
from CVS)
- I am running Xubuntu 11.10 (upgraded today). Was running 11.04 last week.
- Did not see any problems until Monday last week. All worked fine the
previous week.
- When attempting to access the repository via http, the error message
reports permission problems with locking files. I do not see this
error with the native bzr:// method.
- I have no problems accessing the repository from my home machine
(different, but slower network connection).

The error message I got this morning is

address@hidden:~/bzr/emacs/trunk$ bzr -Dhpss pull
bzr://bzr.savannah.gnu.org/emacs/trunk
bzr: ERROR: Connection closed: Unexpected end of message. Please check
connectivity and permissions, and report a bug if problems persist.
