QImage support only one image. This is limitation.

Finaly I found docs for qico image plugin: http://doc.qt.nokia.com/solutions/4/qticoimageformat/
Now it is part of Qt4 package in src/plugins/imageformats/ico/ and is enbaled by default in compilation.

So for reading all icons from ICO file is possible to use class QtIcoHandler and method jumpToNextImage()

I write new patch which will replace using external program icotool in icoutils.cpp
