Hi, Vincent!
Kristian should now how many people downloads each versions. As to why it hasn't been fixed before, a few ideas: people install from the .tar.gz, people install from their distro, people fix it each time, people have another RPM source, people use Debian. Or (it is a possibility, although I think it's very unlikely) Kristian has ignored previous patches.
Actually, I have received the reply from Kristian already. He writes that the patch will be applied. My guess is that there is that most people didn't have time, motivation or qualification to fix this RPM given the existance of alternatives.
But is this list appropriate for questions about third-party Wine packaging?
I'm sorry if it's not.
