problem for 0.6c

[James Bulpin]

I'm responsible for the xenbits.xensource.com Xen repository server 
Xiaofeng Ling mentions in the post. We upgraded the server to 0.6c 
yesterday. A number of people have reported problems with cloning using 
0.6b and 0.6c clients (0.5b seems to work fine). Trying it myself I see 
the same error as the poster using either 0.6b or 0.6c as the client. 
For now I've backed off the server to 0.6b.

Additionally I now see errors with hg verify that I've not seen before; 
0.6b does not show them, 0.6c does. This is the case for the current 
repo and for historical filesystem level snapshots going back to the end 
of June when we first converted to mercurial.

Are these two issues linked? I'm wondering is some historical problem in 
our repository is triggering the clone failure.

Regards,
James

hg verify performed with 0.6c on a repository cloned from 
http://xenbits.xensource.com/xen-unstable.hg using 0.6b as client and server

Original message from Xiaofeng Ling:

more information:
1. The last mecurial version 988:a66e249d77ae has the same problem.
2. clone the mecurial tree itself has no problem.
3. clone the xen tree(http://xenbits.xensource.com/xen-unstable.hg) has
the problem.(I just test local clone, not http)
4. hg clone -U is ok, but then hg co will also fail
