You might try adding something like this to your local settings:
$wgMimeDetectorCommand = "/usr/bin/file -bi";
I had trouble similar to this after an upgrade.

Hallo,
i have upgraded my webserver to Mediawiki 1.11.0 , almost perfect but i can't see my tiff documents. jpeg or png is no problem so LocalSettings.php is good configured for using ImageMagick to created thumbnails pictures
after checking FAQ and debug with $wgDebugLogFile i found this error for all the tiff images
MediaHandler::getHandler: no handler found for image/tiff.
i traced this back to wgMediaHandlers where no tiff images are present
http://www.mediawiki.org/wiki/Manual:%24wgMediaHandlers say's
$wgMediaHandlers = array( 'image/jpeg' => 'BitmapHandler', 'image/png' => 'BitmapHandler', 'image/gif' => 'BitmapHandler', 'image/x-ms-bmp' => 'BmpHandler', 'image/svg+xml' => 'SvgHandler', // official 'image/svg' => 'SvgHandler', // compat 'image/vnd.djvu' => 'DjVuHandler', // official 'image/x.djvu' => 'DjVuHandler', // compat 'image/x-djvu' => 'DjVuHandler', // compat );
this wil results in the script wiki/includes/media/Generic.php for the clas MediaHandler to say "no handler found for $type."
how to configure the wiki for using tiff files again? the previous version was mediawiki 1.8.2 that has no problems with tiff images. wgMediaHandlers is introduced in version 1.10.0
thanks
