Hi Kitty,
I have the same issue with germansidebar on a english mac.
Have you found a solution?

If some of your Sidebar folder has different Language, You can set as OS X language by simply add .localized file in the folder.
For instant, you have different language folder such pictures in Dutch, you can add this file via Terminal

touch ~/Pictures/.localized

this command line make .localized file into Pictures folder and that make your folder name changes to your language.

Hope you can enjoy mac more!!
