[Mediawiki-l] file does not exist: cologneblue?

[Daniel Barrett]

My Apache error log is filling with this message (MediaWiki 1.13.2):

   File does not exist: <path to mediawiki>/skins/cologneblue

I see skins/CologneBlue.php exists but there is no skins/cologneblue subdirectory.  Any idea why this is so?
