QClipboard problem

[de_bug]

In my application i have to copy data to clipboard in text, RTF(Microsoft) and image formats. I copy RTF data like so:

@ QMimeData* mimeData = new QMimeData();
QByteArray ba;
ba.append("{\rtf1\ansi\pard\plain some{\ul text}}");
mimeData->setData("Rich Text Format", ba);
QApplication::clipboard()->setMimeData(mimeData);@

Then I paste data in Microsoft Word - it work fine. But after that if I copy data in clipboard in any other format (text, image) and paste it in Word, I view only few strange symbols, but copy-paste RTF data continue to work correct. In WordPad all formats work correctly.
Drag-and-drop data from my application work correctly only if I don't try drag-and-drop RTF data, in other case drag-and-drop data in any other formats does not work neither in Word nor in WordPad(few symbols), but drag-and-drop RTF data continue to work correct. Sometimes droping not- RTF data to Word or WordPad cause crash.
In both cases(clipboard and drag-and-drop ), the incorrect operation starts only after working with RTF format.

Please help me to fix this problem
P.S. I use QT 4.3.2

You should be using the standard MIME formats (list "here":http://www.w3schools.com/media/media_mimeref.asp )
