Could you please do the following change, repeat the operation, and then tell me what is written in the error page? I've not been able to figure out what was the exception raised from the hacks:AccountManagerPlugin which was triggering this.

I wonder where that might come from.

I'm sorry. The error above was what the fronted reported. This is in the apache error_log

[Christian Boos]

So apparently there are parts of Python which create localized error messages as str object with some encoding (the locale encoding?), and not using unicode objects for that.

Ok, so I think I'll have to apply the above patch.

(Btw, Markus, can you try to apply the patch, as from the line

PythonHandler trac.web.modpython_frontend:   File "/usr/lib/python2.4/site-packages/trac/util/__init__.py", line 108, in to_unicode\n    return ' '.join([unicode(arg) for arg in text.args])

it doesn't look that you applied it, it must be [to_unicode(arg) ... instead of [unicode(arg)...)

[Christian Boos]

Patch applied in r3296.
