dbus library calls abort() if it got a non-expected type passed to it.
---
Changelog:
v4: - Do not touch values_received
- Set wps=true only if WPS info is successfully received
- Set error on all failing type-checks
v3: Fix embarrassing typo
v2: Check against specific type instead of all basic types
