Hi!
It happened to me that a message "could not determine size of resulting image file" popped out when I try to start burning a dvd. When I clicked on "Debugging info" I saw that actually it was because mkisofs wasn't able to burn two files with the same name in the same directory. Well, I renamed it manually and all worked fine.

Why the two names were the same? Because they were two files with a name longer than 64 characters, but equal for the first 64, and beeing trunked to 64 looked the same to mkisofs (version 2.1).

So I think that would be better: 

1) to change that message in something more specific, or, if this is not possible due to mkisofs, then change it to "mkisofs error: please check debugging info", or something like that. :-)

2) to do something in the "renaming policy" of k3b to be able to deal with long similar file names

cheers,
Pietro (sorry for my english)
