[TYPO3] Segment "fileadmin" was not a keyword for a postVarSet as expected!

[Pierre Rouwens]

Hi there,

I use TYPO3 3.8.1 and real_url 1.0.0, in the errorlogs i have this :

Segment "fileadmin" was not a keyword for a postVarSet as expected!

And i wonder what is the best way to handle this ? i don t find anything 
about special configuration for fileadmin...

Thanks a lot for any informations

Pierre
