problems with an arch-converted repo under cygwin

[Baz]

Hi,
I'm fairly new to bzr, and I'm trying to do this under cygwin:
$ bzr get http://www.gnome.org/~jdub/bzr/planet/devel/trunk/ planet

Under 0.7 this bombs out with:
bzr: ERROR: No such file:
u'/home/bewins/planet/.bzr/weaves/db/x_Jeff_Waugh_<jdub at perkypants.org>_Sat_Jan_10_01:24:22_20
04_32569.0.weave': [Errno 2] No such file or directory:

ts.org>_Sat_Jan_10_01:24:22_2004_32569.0.weave.2652.GLADEVBRIAN.tmp'

in .bzr.log this produces:
get_url http://www.gnome.org/~jdub/bzr/planet/devel/trunk/.bzr/weaves/db/x_Jeff_Waugh_%3Cjdub%40perkypants.org%3E_Sat_Jan_10_01%3A24%3A22_2004_32569.0.weave

I saw some traffic on the list about name problems in windows being
fixed in 0.8, so I downloaded the RC and tried that. This gives a
different error:

brian ewins at GLADEVBRIAN ~
$ rm -rf planet; bzr get
http://www.gnome.org/~jdub/bzr/planet/devel/trunk/ planet
bzr: ERROR: A nested progress bar was not 'finished' correctly.
/home/bewins/lib/python/bzrlib/lockable_files.py:107: UserWarning:
file group LockableFiles(<bzrlib.transport.local.LocalTransport
url=/home/bewins/planet/.bzr/>) was not explicitly unlocked
  warn("file group %r was not explicitly unlocked" % self)

And the corresponding snippet from the log:
get_url http://www.gnome.org/~jdub/bzr/planet/devel/trunk/.bzr/revision-store/7c/Arch-1%3Ajdub%40perkypants.org--projects%25planet--devel--1.0--patch-20

into VersionedFileStore(u'/home/bewins/planet/.bzr/weaves/')
[ 2812] Thu 18:27:48.853 ERROR: A nested progress bar was not
'finished' correctly.

I thought I should ping the list since this is happening in the RC.
Folk on other platforms seem to have no trouble with the repo ( see eg
http://www.intertwingly.net/blog/2006/04/20/Planet-Intertwingly ), but
I'll try this out on a mac later.

I don't have any of the 'optional' libraries installed here
(cElementTree, paramiko, etc).

Any ideas? Am I just being thick?

Cheers,
Baz
