If you open the map you see the option to warp to HQ or to a rally point. Use either and you should be teleported and set free. If that doesn't work I think there is a /stuck command which should kill and revive you at the next spawn point.
A little advice: Don't collide with a door with ANY travel power active. Well acrobatics doesn't bug out or at least rarely but flight and super-speed is very dangerous in this regard.
