Please explain the problem.

The one issue I had was QJsonObject failing to sort the keys properly, which 
resulted in a binary JSON output that was malformed (the format requires the 
keys to be sorted because they are scanned by binary search).

I could not reliably reproduce this in a testcase, so it went unreported.

I should also point out that it happened only with GCC 5.
