[bug] bzr: pressing RET on a remote revision in *bzr-missing* buffer fails

In *Messages*, I get:

dvc-default-error-function: `bzr log --revision 531' failed with code 3

In *dvc-error*, I get:

bzr: ERROR: Requested revision: u'531' does not exist in branch:
BzrBranch6('file:///home/naesten/.emacs/dvc/')

It looks like the wrong branch has been associated with the revlog
entry; I found this in the buffer's dvc-revlist-cookie:

(entry-patch
 [cl-struct-dvc-revlist-entry-patch bzr t
				    [cl-struct-bzr-revision-st 531 "Patch from Thierry Volpiatto:
Implemented xgit-push, small fix for xgit-log" "Stefan Reichoer
<stefan <at> xsteve.at>" "dvc-main" "Mon 2009-03-02 21:43:26 +0100" nil]
				    (bzr
				     (revision
				      (local "/home/naesten/.emacs/dvc/" 531)))
				    nil nil nil])
