problem after recreating subversion repository

[meinholz@…]

I am using trac 0.10.4 and python 2.5.1 on ubuntu. I am using the debian/ubuntu pkgs that have been installed using apt-get.

I had to delete and recreate a subversion repository after associating a trac project with the repository. I have run the command:

trac-admin /path/to/tracproj resync

This partially works. My wiki seems to be recovered and I can edit a page. However, after I have edited a wiki page, submitted the change and then attempt a second edit, I get the following error:

Python Traceback

    raise TracError("The 'repository_dir' has changed, "
TracError: The 'repository_dir' has changed, a 'trac-admin resync' operation is needed.

If I re-run the trac-admin resync, I am able to do another edit before the problem recurs.

No, #5788 is about a "No such revision message" error. Here it's a different story:

The 'repository_dir' has changed, a 'trac-admin resync' operation is needed.

In the trac log, at INFO level, there must be a line like:

repository_dir' has changed from /a/b/c to /x/y/z

Can you tell from that what's wrong?

(e.g. that could be a trac-admin resync performed on a different environment than the one used by the web application, when both are sharing the same db but have different 'repository_dir' settings in their trac.ini)
