Description:
Not much to explain. If you use the new stripprefix=1 checkbox at [[Special:PrefixIndex]] and you use an existing page name as the prefix the first link is stripped to an empty string and therefor completely hidden.
http://en.wikipedia.org/wiki/Special:PrefixIndex/WP:WikiProject_Comics?stripprefix=1
The resulting HTML looks like this (no content between <a> and </a>):
<a href="/wiki/Wikipedia:WikiProject_Comics" title="Wikipedia:WikiProject Comics"></a>
Not sure if this should be a "major" bug because it could make you think an existing page does not exist.
Simply solution: Display the unstripped page name in case the stripped page name matches /^\s*$/s. This would be a lot more useful in my opinion than a constant replacement.
