Comment 3 for bug 677929

Milan, I don't know if the urgency of this issue is low.
Ubuntu installer is affected as well, and I've read on forums about some novice user not being able to perform the installation as of this issue.
Anyway, as I wrote in my bug report, perhaps the dot should be removed because it's used by the chown command: "chown user.group <file>", as an alternative to the colon.
