Created attachment 12435 [details] Screenshot showing headline with $1 while the link in the lower left edge is showing a user name in the same place. Both are using MediaWiki:contributions for the message. Pass user name to [[mediaWiki:contributions]] even if used as a headline. See screen shot description.
Your translation is wrong, don't add the username to the title: bug invalid. If you want to request such special pages to have the target in page title, that would be a different thing.
The message descript says that $1 was the user name. The message is used twice: - in one instance $1=user-name works - in the other, it does not. This inconsistent behavior and/or the message descriptin need to be fixed. Either we need to have two independent messages, or they mus behave identically.
Purodha: Do you plan to work on a patch to fix this? (As you said yourself as assignee here.)
