Fixing the traceback (semi-automatic trace report did not help…)

[Christian Boos]

Hm, that was an old style extract_link call.

I'll also check the semi-automatic bug reporting feature.

[Christian Boos]

Fixed in [6143].

The action that triggered the error was:

[Christian Boos]

Sorry, I don't understand how href could be None in source:trunk/trac/wiki/intertrac.py@6149#L50​.

Would it be possible for you to add a couple of print statements in the lines above to get more details about the issue?

I can't do it myself, as your example works fine for me.

Sorry, forgot to update the ticket: yes, the problem is triggered when there's no permission to view or create the targeted page. Then, there's no <a> element given back by the extract_link, but a <span> with some error message.

[Christian Boos]

Should be fixed in [6199].
