Im a linux user and i use JWowUpdater for addon managing. It has this feature: 'Cleans .toc, embeds.xml and other include files so that non existing libs wont slow your loading.'
I traced the lua errors from classtimer wich only occuring since i play wow trough wine and found out the reason,
in ClassTimer.toc defined: 'locales\enUS.lua'
but the actually path is: 'Locales\enUS.lua'
would be nice if you could fix that :)
