I created an app that uses IntentServices to access the database (in my case SQLCipher). I send that between the callers and IntentService using Parcelable objects. Everything ran fine for the last year but after Android 5.0 was released, my app started crashing with a SIGSEGV when it tried to start IntentServices (or operations that had anything to do with the IntentService lifecycle).

Sometimes I also get the line of code where the exception originated from but it's not really helpful. It points to the mContex.startService(mIntent) and the rest of the code looks something like this:
mIntent = new Intent(mContext, EventQueueIntentService.class);
mIntent.putExtra("command", EventQueue.SEND);
mIntent.putExtra("sender",TAG);
mIntent.putExtra("priority", EventQueue.Priority.LOW);
mContext.startService(mIntent);
This phone isn't rooted and I can't get the full Tombstone. I ran adb bugreport but it contains a bit too much personal data.
I usually also get just a piece of the stack/back trace:

The problem appears to be somehow related to the IntentService lifecycle. The only parcels that could fail here are the ones used by IBinder.
Can someone offer me a direction in which to search for the solution?
Thanks, Johnny
