AttributeError: 'ThemeNotFound' object has no attribute '_message'

[Jochen]

Hi,

I'm currently running Trac on Windows XP with Python 2.6. I have 2 trac projects, which can be accessed through Apache HTTPD.

I want to use the same theme in both of the applications, but the theme only appears in the first project I access, after Apache HTTPD starts. When I browse to the other project, I get this error: Warning: Unknown theme littlemary configured. Please check your trac.ini. You may need to enable the theme's plugin.

So it seems to me I can only use 1 theme in multiple projects? The theme is installed as plugin in both of the the projects

How to Reproduce

While doing a GET operation on /admin/theme/theme, Trac issued an internal error.

(please provide additional details here)

Request parameters:

{'cat_id': u'theme', 'panel_id': u'theme', 'path_info': None}
