Hi all,

running a bzr update on a live server yields the following error:

===================================================================

===================================================================

The update process runs all the way up until it's about to display the list of updated files,. The last message I see is something about "pass 10/10".

We have been using this server for months. The project is several years old and very active all the time. 1st encounter with this error.

Naturally, we have to update the LIVE site this weekend. \

Can anyone point me in the right direction? How to I resolve this or get around it safely?

Thanks.
