Comment 13 for bug 365874

Could you attach the relevant part of your .bzr.log ('bzr version' will tell you where it is) after issuing
the failing command adding '-Dhttp' in the parameters ?

That will provide more information about how the bug occurs.
As mentioned in previous comments, this behavior is rare and hard to reproduce, so while the workaround is perfectly
valid, it will be good to better understand the issue.
