It turns out that when looking at realms they found 3 crash bugs in 0.7.3, but they already took care of it in 0.7.4 :D So if you had a problem with Minecraft Pocket Edition crashing when on a server or lbsg, they have now fixed it so hopefully it wont happen again.

They are on a role, anyways 0.7.4 should be out by Monday next week if not sooner or later.
