Please keep in mind that this forum is not a substitute for filing bug reports – bug reports capture more information and provide tracking that is simply not possible via the forums.
As for the back traces you've provided, they don't really provide a lot of information for us to go on as is. If your app is crashing, the OS will write crash logs with significant information for debugging, and these are included in the sysdiagnoses that you will be asked to provide.
In addition to that, if you can narrow the issue down to a sample, thats often extremely valuable to us for tracking down issues as it can still be difficult to come up with a solution without the context of what is being done, but if that isn't possible we're still happy to get the bug report.
So far there isn't much we can recommend here, so as was previously mentioned, filing the bug report with the requested information is your best next step.
