Hello,
Actualy had some netowrk problems here yesterday, so if you sent me any
replies yesterday I didn't receive it, but don't see any reason why the
troubles should have caused the loss of any Email.
Anyway over the past day I have had yet two more crashes, and wasn't sure
if any of this info would be of any help or not. I will include the two
backtraces below, and if having any more would help, or you need any other
info please let me know. As I am sure you can tell this is just driving me
up a wall.. :(
