sure, see below for the backtrace; however, i've got some clues about
what's going on and if i'm right it's not really Emacs' problem but my
dodgy practice of copying the workareas around

so the wider picture is like this - at work we have a project with a
Bazaar repository sitting on a LAN PC and most of people using
'lightweight' Bazaar checkout (i.e. no local history of changes).

to complicate things further the application builds under both GNU/Linux
and Windows so people will have two checkouts in their respective OSes

i don't have access to office LAN from home and sometimes i zip the
whole workarea in order to (mostly) read code living in the dark corners
of the project that i know very little about; well i was convinced i've
zipped up the GNU/Linux workarea, but that's probably not the case; once
unzipped on my home Debian PC the .bzr points to a badly formed path
(i.e. starting with Windows drive letter + the ':' character which is
mapped to a network drive/directory) to the Bazaar repository; well, it
looks like this confuses the hell out of 'tramp' when trying to look at
this repository;

i'm fairly confident this is the cause of the problem; apologies for all
the confusion caused

i forgot all about the 'lightweight' checkout (it was fist performed
years ago when the project started) until Eli mentioned it in the
Emacs-Help group/list

not sure if you guys want to address this "issue" but here's the
backtrace as requested
