Placeholder issue: Going to check forum links

I did believe that Category 6.x-2.0-rc1 works fine with core Forum module (apart from initial creation of forum vocabulary needing to be done *after* taxonomy wrapper is installed, and apart from playing with settings on the corresponding container node being dangerous), but after I put my site online, I noticed something weird about the taxonomy-style links to categories, shown on my forum-topic nodes. These were linking to plain category pages, not to forum overviews (i.e. links not translated to forum-specific).

I'm not sure in which exact situation this happened (as I soon removed these links on forum posts altogether, in my theme, for an other reason), so setting this issue to a task assigned to myself now, in order to verify/investigate what really happens. I'm going to turn this into a bug report later, if there's indeed a problem.
