iOS8 Runtime Crash (iPhone/iPad REAL Device)

I have an App that works perfect in iOS7.
I'm experiencing some problems when I want to run it on iOS8.

Some XCode debug info:

Thread 1: qioseventdispatcher.mm with an EXC_BAD_ACCESS

I attached a reproducible test-case (qtios8test.zip)

I think the problem may be in the resource loading process, because the resource files are heavyweight.
