I've upgraded TagsPlugin to latest trunk version with following devastating effect:
- NotImplementedError on any ticket page - full DoS
- NotImplementedError on any wiki page, as soon as I try to edit - partial DoS
Analysis the provided Traceback led quite straight-forward to disabling the KeywordSuggestPlugin installed there as well. Effect: Full recovery minus keyword suggest functionality, naturally.
This seems to be a regression in Tag query functionality, but as our users really like/need this for everyday work to prevent tag bloat by misspelling/casing-only differences/etc. I've made a quick hack to restore it.
Publishing this is mainly for reference to serve a temporary solution. To fix this inside the TagsPlugin will be the preferred way, but much harder to be done, as the query module there is a different piece of cake, or I've just not tried hard enough.
