formatter.py: wiki_to_onliner sometimes returns '' and sometimes returns a Markup

[stevemccusker@…]

If it returns then text.plaintext fails in line 466 of formatter.py.

This was causing reports 1,2,3 and 8 to fail. This is one a Trac I setup as a learning and evaluating tool. The reports had not been changed. However I had two other Trac projects set up as tests and they were OK.

By changing line 1000 in formatter.py from

    return ''

to

    return Markup('')

the problem was fixed.

I am using version .10dev as I am experimenting with better control over ticket visibility for some potential clients who are software developers who do not want their clients to see any tickets but the ones they submitted themselves.

The Traceback follows.

I am using version .10dev

… and that's a bit old by now ;) The problem you describe has already been fixed (r3397).

And by the way:

I am experimenting with better control over ticket visibility for some potential clients who are software developers who do not want their clients to see any tickets but the ones they submitted themselves.

See #3466.
