Of course. There's a new feature in QVariant and the metatype system relating 
to enums. So it's going to work on the newer versions but not on older ones.

That said, the information I can find indicates the feature was introduced in 
5.5. So it should have worked on all of your tests. Conclusion: the problem is 
not where you're looking.

Please attach a simple[*] testcase so we can investigate further.

[*] simple is: a single .cpp file, less than 200 lines of code, that compiles 
and is self-sufficient. No need to attach the .pro file.
