Next time you go to do that and it doesn't work, activate your Portal Wand. Then cancel before making any selection. Talk to the Tarkuul portal again. If that works, then just keep that in mind and use that the next time(s) that happens. If it doesn't work, let us know, it's probably related to some other script issues with portals we've been having, and that'll be good to know for certain.
Problem still persists after the portal wand trick. I chalked this up to the plot with the lamps so I didn't report it at first.
