Unknown; I would suggest enabling gref logging:
# http://docs.xamarin.com/android/advanced_topics/diagnostics
adb shell setprop debug.mono.log gref
Then, when your app crashes you'll see:
I/dalvikvm(11680): JNI ERROR (app bug): accessed deleted global
reference 0xea6007fa
You want the JNI reference handle value -- in the above 0xea6007fa -- then
search backward in the logcat output to see if that handle was ever deleted:
I/monodroid-gref(12405): -g- grefc 107 gwrefc 0 handle 0xea6007fa...
If you see such a -g- message, then look at the stack trace to see where it's
being disposed; hopefully it's in your code and you can fix it. ;-)
If you don't see any -g- messages for the "deleted global reference" handle,
try to create a repro and file it at bugzilla.xamarin.com so I can investigate.
Thanks,
