Are you familiar with the concept of a stack trace? What you are looking at are the lines of code execution from the crash (0) back to a recent frame entry. As such, this is referred to as a 'back trace' since it goes backwards from the point that the code stopped executing.
I have no knowledge of your code, but you can see from line 14 of the back trace that you received a low memory warning. This warning caused a chain of unload events, including a deallocation of a UITableView (line 3).
This is immediately followed by the _sigtramp, which probably indicates an EXC_BAD_ACCESS. My guess, without seeing the rest of your code, is that you are accessing something that has been released by the low memory unload situation.
