Are you running/using any custom third party apps?  What we're seeing in
your backtrace is corruption of your channel variable list.  Basically
something is getting added to your channel variables (before this one) that
contained out of bounds addresses, and while checking to see if the
variable was already set, it came across that record and segfaulted.
