Cannot inspect contents of QMap on Symbian

I have a QMap in my code:

QMap<QString, QString> someMap;

someMap.insert("1", "one");
someMap.insert("2", "two");
someMap.insert("3", "three");

When I break in the last of these lines, Creator shows "<2 Elements>". When I try to expand this and to see these two elements, the string changes to "<unavailable synchronous data>".

This is a regression, it works fine in 2.0.1.
