Internal Error when submitting a review

[roxana.macarie@…]

I'm using Trac 1.0, via Apache. Installation seems to go well and differences on the changesets are shown, but when I try to submit a review on a changeset I get an internal error:

AttributeError: 'NoneType' object has no attribute 'get_changeset'

... = I substituted the path to the file.

We have multiple repositories set, but a default repository is defined.

I do not have that much experience with python, so any help would be appreciated.

How to Reproduce

While doing a POST operation on /changeset/141/moduletest/..., Trac issued an internal error.

Request parameters:

{'__FORM_TOKEN': u'6cea3ac5ccb4e7227f291cfb',
 'new': u'141',
 'new_path': u'/moduletest/...',
 'reviewbutton': u'Submit review',
 'status': u'PASSED',
 'summary': u''}
