I think the answer is right there in the crash report:

<RBSTerminateContext| domain:10 code:0x8BADF00D explanation:[application<com.mkwe.uusafe.com.safemail>:2853] failed to terminate gracefully after 5.0s

You're also executing the table query twice. Things would probably go faster if you only did it once.
