Viewing a subversion version by viewvc which is not related to mediawiki but to pywikipedia a link to a mediawiki code review exist. But this should not. A solution would be deactivating that link if the root is not mediawiki.
Example:
http://svn.wikimedia.org/viewvc/pywikipedia?view=revision&revision=8086
leads to this code review:
http://www.mediawiki.org/wiki/Special:Code/MediaWiki/8086
which has noting to do with pywikipedia.
Version: unspecified
Severity: minor
