AccountManagerPlugin won't work when used with mod_wsgi

[anonymous]

Hi there,

I am playing with my Trac setup and thought I could enhance the spped a bit more by using mod_wsgi for serving the pages. All is working fine until I enable AccountManagerPlugin.

When accessing the page, I recieve a 500 internal server error. The apache2-logfile is attached.

in /tmp/ I find: TracAccountManager-0.2.1dev_r3857-py2.4.egg-tmp - should this be removed? Inside this path I find several html-pages, which seem to be cached for server-delivery.

When I disable AccountManagerPlugin all is fine again. I just checked it against tracd, and there even AccountManagerPlugin is doing fine.

I'm running a debian-etch server with mod_wsgi from etch-backports.

The reporter emailed me this info from the log

This appears to be a general bug in the trac.wsgi file trying to set the temporary path where plugin resources are extracted. Please file a ticket against Trac about this, since it's not specific to this plugin.
