Can't remove file ... error when merging changes to a single file

Try this:
 
svn co svn://svn.reactos.com/branches/xmlbuildsystem/reactos/bootdata
cd bootdata
svn merge -r 12735:13510 svn://svn.reactos.com/trunk/reactos/bootdata/icon.ico icon.ico
 
Subversion gives me an error:
svn: Can't remove file 'icon.ico.2.tmp': The system cannot find the file specified.
 
This works however:
svn co svn://svn.reactos.com/branches/xmlbuildsystem/reactos/bootdata
cd bootdata
svn merge -r 12735:13510 svn://svn.reactos.com/trunk/reactos/bootdata .

The first procedure should be possible right?
