Redmine

Hi,

I use Redmine with a subversion repository.

When I try to view differences with a file with accents, I have this message :
The entry or revision was not found in the repository.

I have five project/folders in SVN repository ; and all are connected to Redmine Repository Tab :

Three projects work fine and I can se repositories from Redmine and differences ..

But with other two I have problems: I can not see difference in files in Repository Tab .. I realised that it may be because I recently renamed root folder of that projects on SVN server ..
And maybe this is because : Redmine look in History (old Revision) for link to that file but old revision has different root folder then as it now ; and Redmine can not find that file on SVN .. (??)
