I can confirm this bug since I use multiple profiles using --no-remote. Usually, when I click on a link in thunderbird when I have multiple profiles open, it is the first profile that was opened that gets to open that link.
Recently (in firefox 3.5.5 on ubuntu 9.10) I have been getting "already running, but is not responding" error when "profile is in use. There is a meta-bug open on Launchpad about this issue: https://bugs.edge.launchpad.net/ubuntu/+source/firefox-3.5/+bug/308605
