initenv crashes: unable to create a trac environment for my project

[clive@…]

Repository indexing fails. There is nothing wrong with the repository according to svnadmin.

Then trying a resync I get the same (if with less detail) error:

% trac-admin test resync
Resyncing repository history...
Command failed: svn_time_from_cstring() argument 1 must be string, not None

starting up the environment (with tracd) then browsing to timeline now gives:

source:tags/trac-0.9.6/trac/versioncontrol/svn_fs.py@#460:

    date = self._get_prop(core.SVN_PROP_REVISION_DATE)

It seems that in your case, the revision property svn:date is missing. While waiting for the fix, you can try to reset it manually (see http://svn.haxx.se/users/archive-2004-03/1370.shtml).

Should be backported to 0.10.1 as well.

Fixed in all 3 branches in [3858:3860] (r3860 should have read backported to 0.9-stable, of course ...)

Note that the fix for 0.9.7 was exceptional, usually we simply tell people to upgrade to the latest stable version ;)
