Hmm, putting it bluntly: your concept of relying on two different parsers 
(with different behavior) handling some arbitrary ini file format is 
flawed. I wouldn't even call this a bug. It's simply unpredictable 
behavior. If you really want predictable behavior, get rid off one of them.

Since logging needs only a few parameter, why don't you fetch them via 
QSetting and pass them on to your logging setup. And because logging has a 
somewhat strange idea of log levels, you have a good chance of translating 
them for human consumption (or even adjustment). 

We could then migrate this discussion to the more general one: 
 - best practices in handling config data, default values, etc.
