A new Scenegraph renderer was integrated for 5.2, and it's has caused
a few asserts. Thanks for testing the beta, we've squashed a lot of
those already and so you should retry with the RC when it comes out.

That's just a bug in Qt :) .
As a workaround in most situations, set highlightRangeMode:

Technically there is no behavior compatibility guarantee between
QtQuick 1 and QtQuick 2, but we tried to keep the differences short
and document them all here:
http://qt-project.org/doc/qt-5.0/qtquick/qtquick-porting-qt5.html . If
something's missing on that page, it should be added. Not sure if bugs
qualify though, I'd rather just fix them than amend the docs.
PS: interest at qt-project.org is probably a better list for asking about
bugs and behavior, I recommend using that list next time.
