Reference to non exists version

[antonio.beamud@…]

All works perfect until now. I'm using Debian etch (trac version 0.10.3) last update and now when try to access my trac, the next message appears:

Traceback (most recent call last):

SubversionException: ("Reference to non-existent revision 1 in filesystem '/var/svn/dummy/db'", 160006)

Trying to resync with trac-admin give me the same result:

trac-admin /home/domains/trac resync
Resyncing repository history... 
(this will take a time proportional to the number of your changesets)
Command failed: ("Reference to non-existent revision 1 in filesystem '/var/svn/dummy/db'", 160006)

This feels almost exactly like #4937 which a lot of people have reported after upgrading to etch, but the error message is different (what version of the svn bindings are you running?).

If your repository is empty, it's a dupe of that issue, which is fixed in 0.10.4 (available in testing and unstable). If not, we need more info. Can you run svnadmin verify /var/svn/dummy successfully?

[antonio.beamud@…]

Well, mi subversion repository was empty. I fixed this problem creating a file in the repository and automatically trac began to work fine… My subversion version is 1.4.2dfsg1-2 python-subversion is 1.4.2dfsg1-2

Hope this helps.

Yes, glad you were able to work around it until Debian ships the new version.
