Hi,
I'm getting the following error message from Qt5's port of Trojita:
QMetaType::registerType: Binary compatibility break -- Type flags for type
'QList<QSslError>' [1062] don't match. Previously registered TypeFlags(0x7),
now registering TypeFlags(0x107).
The backtrace leads back to the constructor of QNetworkAccessManager:

My code contains calls to:
qRegisterMetaType<QList<QSslError> >("QList<QSslError>");
There are no calls to Q_DELCARE_METATYPE or Q_DECLARE_TYPEINFO mentioning
QSslError or QList<QSslError> in my code.
According to the error message, the extra type flag being set is the
WasDeclaredAsMetaType (which is not documented in the docs available on the web
[1] for some reason). I won't pretend I understand the metatype system enough
to tell whether this particular flag shall be ignored or not. The weird thing
is that I recall that my code has worked at some time...
What should I do to restore functionality under Qt5?
With kind regards,
Jan
