MediaWikiPlugin raises AttributeError: 'NoneType' object has no attribute 'groups'

[anonymous]

While displaying a wiki page, which begins with calling the MediaWiki renderer and ends with closing it, trac raises a AttributeError: 'NoneType' object has no attribute 'groups'

I'll try to attach the broken wikipage which can be loaded with trac-admin . wiki load /tmp/directory where that file relies in /tmp/directory.

wiki page exported from MediaWiki which breaks Trac+MediawikiPlugin

patch to prevent runtime error if the mediawiki macro encountered a less-than ("<") sign

[anonymous]

allow_lessthan.patch​ fixed the problem for me. The problem occurred whenever the mediawiki processor would encounter a "<" in your text.

Oh and BTW, I am running Trac 0.12.2. (I see this ticket is against 0.10.)

[Chad Trytten]

Running Trac 1.2.3; confirmed that applying the above patch prior to plugin install corrects the identified issue, which was blocking essentially every MediaWiki import for us.
