1. Changing Component from "Single Signon" to "Autofill" 2. I presume you selected amazon.html from the wallet samples menu and then pressed quick prefill. I just tried that and it worked fine. So what are we doing that's different? Is anyone else seeing this behavior?

dp and I figured out that the thing that was different between what each of us were doing was his database. He mailed me his database and then I was able to duplicate the crash. The fix is simply changing the name of a local variable in a procedure because it was conflicting with one of the parameters to that procedure. With that change, the crash is gone. I am now waiting for approval from chofmann to check this fix in to the M3 release.

Approval has been received -- fix has been checked in (wallet.cpp).

Verify in the M3 build
