bazaar bug with bzr+ssh:// and pack-0.92 format

[David Ingamells]

I have a repository that I haven just upgraded to pack-0.92 format. When 
I run the following command

bzr cat bzr+ssh://mscvs01/data/id/CmsRoot/repos/MScms/1.0/.cmsmanager.ini

I get the error log below. (bzr versions 1.2 and 1.5 both do it). If I 
upgrade back to dirstate-tags it works again.
The access method file:// works with both formats ( but obviously only 
on the local machine ;-) )

Has this been fixed already in 1.6?
How thorough is the (regression) testing of the different URL prefixes? 
If people are going to be telling us that we should upgrade to the newer 
format then they should be sure that support for the format is robust 
across the board.

Conclusion: I am forced to keep the format at dirstate-tags and am now 
very concerned about the performance problems with bzr branch using 
version 1.6beta2 and this format that I reported in this forum on 11/7 
in "Re: Some timings using bzr" (these are in seconds):

                           file://NFS                      bzr://
dirstate-tags              220 / 198                       552 / 39
pack-0.92                   48 / 47                         59 / 37
