Is there any helpful information in this crash report?

I am trying to identify the cause of a crash (iOS app), but the symbolicated crash report only points to my main method. 

8   WxT                               0x00002730 main (main.m:14)
9   WxT                               0x000026e8 start + 32

Is there anything here that could help me track down the issue, or is this as useless as it appears to me? What does the "start + 32" tell me?

N.B. my app is WxT, and it only referenced a few times in the report. I've highlighted each occurence with a double asterisk (**).

The error message states you tried to run for more than 10 minutes while in the background. By default, iOS apps must stop all processing within 10 minutes upon being put in the background.

It looks like:

Application Specific Information:
**WxT[3214] has active assertions beyond permitted time:** 
{(
    **<SBProcessAssertion: 0x14005c20> identifier: Suspending process: WxT[3214] permittedBackgroundDuration: 10.000000 reason: suspend owner pid:23 preventSuspend  preventThrottleDownCPU  preventThrottleDownUI** 
)}

the system is trying to move your app to background, and your URL connection (thread.3) is preventing that from happening.
