[Interest] QTreeView header move first column doesn't work.

[Igor Mironchik]

Hi.

On previous versions of Qt moving first column in QTreeView worked.

But when I updated Qt to version 5.1.1 it has stopped working.

All other columns moves with user's interaction correctly except first 
column.

What is the reason of this problem?

May be there are appeared new API?

Can you help me? Thanks.
