AIR for iOS application crashes with sig 11 after update to air 17.0

I have an app that I am trying to update.

The last air sdk used was 3.8 and now I am trying to get it to work with 17.0

I am using command line to compile, package, and install app on an iPad which all seem to work just fine.

When I run the app, it crashes pretty quickly. Crash report says Exception Type: EXC_BAD_ACCESS.

I though it might be related to the anes so I removed all of those and am still having issues.

When I hook it up to to fdb and use "catch *" sometimes I will get

"[Fault] exception, information=ReferenceErro: Error #1065: Variable FlexVersion is not defined.

Fault, SpriteAsset() at SpreteAsset.as:131

     if (appDomain.hasDefinition("mx.core:FlexVersion"))

Other times it will just terminate with no information.

Any ideas what I am doing wrong?

am using 17.0 namespace, flex 4.6, target-player is 17 and swf-version is 28.
