Double check that your base_url option is well defined in your trac.ini file. See also #4105.

Changing the base_url helps. Why is this necessary when everything else works without this?

Well, because it's a tiny bug ;)

Fixed in r4245, but as Emmanuel said, the base_url setting is now nearly mandatory. Perhaps this should be made more apparent in the docs.

I think we should start a TracDev/ReleaseNotes/0.11 page...

I don't know the internal details so the following suggestion might not be applicable: would there be any way to infer the actual value from other parameters such as TracUriRoot? It seems that the base url parameter needs to be replicated in both the web server configuration file and the trac configuration file, maybe one of them could be retrieved from the other one?

The base_url information is effectively derived from the web server configuration in a few situations, and can also be generally recovered from the URL itself (see source:trunk/trac/web/api.py@4245#L152), but there are a few situations where we don't have access to the req, and then the only possibility is to use directly env.abs_href which makes use of the base_url info.

I'm pretty sure I miss an important point, but base_url is not tied to a request: it's a static value. Is there no possibiilty to retrieve this value at startup and keep it in the environment, for example?

Actual problem fixed in r4245. If needed, the base_url discussion should be moved elsewhere...
