If you watchlist a page with a name beginning with "Talk:Foo:", where "Foo" is a namespace prefix such as "User" or "Image", the page cannot be unwatched via Special:Watchlist/edit, since it will be listed without the "Talk:" prefix. Such pages are occasionally created, usually by mistake, and may end up in the watchlists of new page patrollers. Simply including the "Talk:" prefix in the checkbox value attribute in such cases would be sufficient to fix the problem. http://bugzilla.wikimedia.org/show_bug.cgi?id=2871 is related to this bug, but neither depends on nor blocks it.
Hallo Ilmari, This aplieas also for interwiki prefixes. See: http://wikimania2006.wikimedia.org/w/index.php?title=Talk:En:&action=watch http://wikimania2006.wikimedia.org/wiki/Special:Watchlist/edit Use http://wikimania2006.wikimedia.org/w/index.php?title=Talk:En:&action=unwatch to remove 'Talk:En:' from the watchlist. Because 'User:', 'Image:', etc. '<interwiki_prefix>:' are invalid titles I would suggest that 'talk:User:', 'talk:Image:', etc. 'talk:<interwiki_prefix>:' should be invalid titles as well. This is probably another bug / request. "complications" http://wikimania2006.wikimedia.org/wiki/Talk:Special:Allpages is a title which reminds Bug 509: Multiple namespaces confuses some users. best regards reinhardt [[user:gangleri]]
Such titles are now invalid as of r45389
OK, someone can run cleanupWatchlist.php to clear these out
This is doing really weird things, like normalizing 'Talk:Wikipedia:Foo' to 'Wikipedia:Talk:Foo' which then redirects me to 'Talk:Foo' at Wikipedia. Need to create some test cases for this if it's redone. Reverted in r45479
I assume (In reply to comment #4) > This is doing really weird things, like normalizing 'Talk:Wikipedia:Foo' to > 'Wikipedia:Talk:Foo' which then redirects me to 'Talk:Foo' at Wikipedia. I assume that's on a default install, where "wikipedia" is an interwiki prefix? I'm not sure what it should do, then, given that "wikipedia:Foo" is not a valid local title, and thus cannot meaningfully have a local talk page.
...but yes, it's probably broken: if I tried that on my Finnish-language test wiki, it would turn "Keskustelu:Wikipedia:Foo" into "wikipedia:Keskustelu:Foo" and then try to go to "Keskustelu:Foo" on the _English_ Wikipedia. Probably it should just treat titles of the form "Talk:interwiki:Foo" as invalid.
(This was redone in r45780) Better, but not quite there; it's still allowing pages like 'Talk:Wikipedia:Foo', for which 'Wikipedia:Foo' is an interwiki link.
Changing component to "Watchlist"
One also should run cleanupTitles.php: see http://mid.gmane.org/7c2a12e20903121355j587246e2ma68fec54f79d6e17@mail.gmail.com , Bug #11487.

No.
Rather -- shell tag indicates a need to run a database cleanup to clear out existing bad entries. This bug also includes fixups to forbid the half-bogus pages to begin with, which is not a shell issue.
This also applies for custom namespaces - if you watchlist a page in a pseudonamespace, and that pseudonamespace is later added as a custom namespace, you end up with one of these invalid watchlist entries. These titles can be removed in Special:Watchlist/raw by copying the list of titles into your text editor of choice and removing the offending title(s) from the pasted list, blanking the list in Special:Watchlist/raw and saving it (thus blanking your watchlist), and then pasting the modified list back into Special:Watchlist/raw and saving again. Pseudonamespaces may not be much of a problem on Wikimedia wikis, but are more so on Wikia (where I observed this variant of the bug and figured out the solution), and definitely on other third-party installations.

Fixed in r111085.
