[The bug is a]lways reproducable, affects both versions of the Linux demo, seems to affect every transporter. Squad goes in, squad goes across, squad doesn't come out the far side, screen goes yellow, have to hit ctrl-c to kill the squad and then everything goes back to normal.
He's running Debian Sarge, nVidia GeForce FX 5200, Athlon 1.2GHz.
I'd not seen this mentioned elsewhere, though I guess it's always possible that I've just looked straight past an obvious report of it.
