[LAU] Ardour... now with extra connections???

Tech details: Fedora 9/CCRMA based system, Delta 1010, 2.6.26.8-1.rt13.4.fc9.ccrma.i686.rt kernel (usually) jackdmp 1.9.1, Ardour 2.7.1 (both pre-built and hand-compiled) /usr/bin/jackd -R -P70 -p512 -dalsa -r44100 -p128 -n2 -D -Chw:0 -Phw:0 -m Prologue: it helps to understand that in my Ardour sessions, I have the master bus output going only to the monitor bus, and the monitor bus outputs connect only to the system:playback inputs. I then control the volume to the powered monitors with the fader for the monitor bus. I started up an Ardour session today to listen to a band I'd recently recorded with Ardour 2.7.1, and heard feedback that started quietly but started growing rather quickly. I turned down the amp and saw the master bus's VU meters full on into the red, with the monitor channel about half that. I pulled up the master bus input list and saw this: in 1 ---- ardour:Drum Submix/out 1 ardour:Bass/out 1 ardour:master/out 1 ardour:Vox FXout 1 ardour:Marty Guitar/out 1 ardour:Harry guitar/out 1 in 2 ---- ardour:Drum Submix/out 2 ardour:Bass/out 2 ardour:master/out 2 ardour:Vox FXout 2 ardour:Marty Guitar/out 2 ardour:Harry guitar/out 2 'Ere, what's all this then? Master outs in the master in? That ain't right! So I click on the master/out 1 item, and it goes away. I click on the master/out 2 item, and it goes away... but it brings back the master/out 1 item. WTF? I open the master outputs, and see this: out 1 ----- system:playback_1 system:playback_5 out 2 ----- system:playback_2 system:playback_6 Ports 1 and 2 are fine, but 5 and 6 go to the mixer. Odd, but it shouldn't matter, since the mixer's got everything down right now. Let me just remove playback_5, I don't need it. Now for 6... oh sh!+, I take 6 out but it pops 5 back. What's in the monitor input? in 1 ---- ardour:master/out 1 ardour:auditioner/out 1 in 2 ---- ardour:master/out 2 ardour:auditioner/out 2 Auditioner? Do I use it? let's try and remove it.... Nope, I can take one out but the other pops back. Oddly enough, the real buses are fine. I can remove the monitor inputs from the master outputs fine. It's only these odd ports that I haven't used in the session. I've opened other sessions and found the same problems. If I look at the session.ardour file, there's no mention of the Auditioner or the playback 5&6 ports. Not weird enough for you yet?? I just opened the session under another login on the system (non-root), and it's fine. No oddball non-removeable ports, no feedback, no problems whatsoever. Anyone got a clue as to what's happening here?
