I was trying to checkout two trunks in two xterms.
http://clojure.googlecode.com/svn/trunk/
and
http://clojure-contrib.googlecode.com/svn/trunk/

The first checkout (clojure) started out fine but the second (clojure-contrib) failed with the error below:

    [parth:src]% bzr checkout http://clojure-contrib.googlecode.com/svn/trunk/ clojure-contrib

This (clojure-contrib checkout) worked fine the second time. However when I look at the first (clojure) window I observe that the clojure checkout has failed now, with the same error. Is bzr-svn not supposed to be used concurrently? I understand debian/lenny has an old version of bzr (1.5) - I tend to stick to apt. Is this something thats fixed in a new version?
If not running concurrently is a constraint, thats ok, but maybe the message can be better?

Below is the error I saw in the first window (clojure) once I started the checkout for clojure-contrib for the second time.

Thanks very much.

PS: Great job with bzr. I really like bzr, its usability and the focus of the dev team on correctness. Thanks.

Just tried this again. This time without running two checkouts in parallel but saw the same issue. Not sure if this has anything to do with running them in parallel as I thought earlier.

svn co seems to be working fine.

This does seem to be an intermittent error that does happen with with svn also. Doesn't look like this is bzr related.

[parth:src]% svn co http://clojure-contrib.googlecode.com/svn/trunk/ clojure-contrib
svn: Server sent unexpected return value (502 Bad Gateway) in response to PROPFIND request for '/svn/!svn/vcc/default'

Got the above error the second time I tried to do the checkout.
Sorry for the false alarm.

Another thought. Should the last few lines of the error message be changed in such cases to indicate that its not really a bzr error (if there is a way to be sure of that?)

Maybe an error message can be show followed by a clean exit.

Thanks again.

No problem, but you may want to file a bug against bzr-svn or, may be better, again svn itself.

No real way to be sure, we can't even be sure that it's due a plugin...
