I've tried your example. My understanding is that the problem happens 
when the CharFormat is applied to a piece of text that happens to 
coincide with the current selection.

Try to clear the current selection, in addition to textedit ->clear()

  QTextCursor c = textedit->textCursor();
  c.clearSelection();
  textedit->setTextCursor(c);

Best regards,
