problem during a merge

Hello to the community

I have an error during a merge and I don't understand the meaning of
this error.

I'm trying to apply the modifications done on a trunk to my local
working branch :
svn merge -r 25:150 https://ipadress/therepository/trunk/src ./my_branch/src
Everything works fine untill the merge process is trying to work with a
new file added in the https main repository.
The merge operation stop giving me this message:

"svn : Schemas d'accession mixtes non encore supportés"

What we can try to translate into something like:
"svn: schemas of mixte accession not yet supported".

Does anybody knows what this message means ?

Thanks for any help
