[Mediawiki-l] File Link Extension Bug

[Tech Geek]

So I have been looking for an extension which can open a dialog box and a
user can browse/select a file that they want to link in the Wiki page using
the "file://" protocol. I finally found one extension [1] which claims it
will do the job. So I followed the instruction on how to use it and then
when I went to load my wiki home page I get the following error message
after enabling the detailed debugging information feature
($wgShowExceptionDetails = true;):

Detected bug in an extension! Hook filelinkDo failed to return a value;
should return true to continue hook processing or false to abort.

Backtrace:

#0 /usr/share/mediawiki/includes/Parser.php(378):
wfRunHooks('ParserBeforeTid...', Array)
#1 /usr/share/mediawiki/includes/Article.php(3174): Parser->parse('==
Welcome to {...', Object(Title), Object(ParserOptions), true, true, 1189)
#2 /usr/share/mediawiki/includes/Article.php(821):
Article->outputWikiText('== Welcome to {...')
#3 /usr/share/mediawiki/includes/Wiki.php(390): Article->view()
#4 /usr/share/mediawiki/includes/Wiki.php(48):
MediaWiki->performAction(Object(OutputPage), Object(Article), Object(Title),
Object(User), Object(WebRequest))
#5 /usr/share/mediawiki/index.php(90): MediaWiki->initialize(Object(Title),
Object(OutputPage), Object(User), Object(WebRequest))
#6 {main}
Any ideas how can we resolve this error message? I am using Mediawiki 1.12
on a Debian Linux PC.
