Comment 8 for bug 1371166

Ok, I think I know what’s going on: qtubuntu-sensors provides position updates with a horizontal accuracy set, but it’s set to something that’s not a number (NaN). According to QGeoPositionInfo’s documentation, if an attribute is not set, querying its value will return NaN. But in that specific case the attribute is set, so I think it’s reasonable to expect the value is a valid number. It looks like qtubuntu-sensors could be patched to ensure it’s not setting invalid values on attributes. oxide can also be patched to test the attributes and discard those that are not valid numbers.
