Decipher iPhone crashlog

I got a crash for my own app on my iPhone, and am trying to figure out what happened. Here is the relevant part from the crash log in Xcode (sorry for the poor formatting):

Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Exception Note: EXC_CORPSE_NOTIFY Triggered by Thread: 0

Filtered syslog: None found

So I do see some errors but they are all non-specific, not pointing to a specific call.

Can I extract more info from this log or somewhere else to figure out what could have gone wrong?
