Comment 7 for bug 246233

Not sure of the current status of this one, but it also applies to commits to a bound branch when the parent bzr+ssh branch is inaccessible. I'm using Bzr 1.10 on Cygwin, so a bit old; apologies if my info is out of date. I just got this when committing to a bound branch when the parent's server happened to be temporarily offline (names/project references genericized):

Doug 2% bzr commit -m "Skeleton file set."
