1.15.1.3 crash on login

Seems, superficially at least, like a problem I've been having since 1.14.* where I get through the login screen and after waiting for the progress bar to fill, the client crashes before getting into the world.

This is after deleting ~/.secondlife and running the freshly unzipped client.

Crash report submitted, but here's some other details:

Using 1.15.1.3 on both Arch Linux and Fedora Core 6, teleportation fails with either a "Could not teleport" message or takes forever to load and then says I can read my chats and IMs but to do anything else, I'd have to restart. When I do, I start in the same place I started in the time before.

Also, while flying, I will occasionally just fly in one direction and be able to move my camera but not my avatar. I will keep flying in this direction forever until I close the game. : )

Also, sometimes, my avatar doesn't care about surfaces and just sinks through them forever (homes, floors, etc.)
