The problem is that it is in kdebase. So it needs its own .pot file and then 
to ensure that the right catalogue file is loaded at runtime. As I do not 
really know how much complex this way would be, I thought that adding a new 
message code would be easier.

Well, I had a thought in such a direction too. However that can only be done 
in KDE 4 as it is BIC. (The idea was to give even more precise error messages 
by making KZip return error codes instead of true/false.)

As for what an application could do with ERR_UNSUPORTED_FILE_FORMAT, well, i 
do not know, Probably most applications will drop the error code anyway and 
simply display "Could not open file %1" without passing the KIO error.

Have a nice day!
