Sounds familiar, yes. Happens occassionally, probably only if
versioned alternative dependencies in combination with conflicts are
involved. Which exists a bunch of times in Debian, but you probably
can count the cases on two hands.
(IMHO only a minor issue easy to workaround interactively, but I'll
leave it on normal and would like to hear Manuel's opinion on it.)

Not really. At that moment neither of the two alternative versioned
dependencies are fulfilled, hence it tries to fulfill the first
alternative dependency. The remainder seems to be a "local optimum"
issue it doesn't find to escape itself in time. It probably will find
the right solution later if you continue to request alternative
dependency solutions with ".".
