No error message when adding file with mixed line endings

Hello,

I try to add a file in a working copy with mixed line endings (CRLFs and LFs), e.g. attached test.h.

The config file has the following entries:
[miscellany]
enable-auto-props = yes
[auto-props]
*.[Hh] = svn:eol-style=native

When adding the file in a working copy nothing happens whereas in a command line the following error message occurs:
svn: File 'test.h' has inconsistent newlines
svn: Inconsistent line ending style

The same error message occurs when adding the file via the repo browser.

Would it be possible to also have the error message when adding the file in a working copy?

Thanks
George
