So, you must pass a QIcon.

Now, the doc of QIcon:
http://www.riverbankcomputing.com/Docs/PyQt4/html/qicon.html

Oh, the list of supported file format is described separately in:
http://www.riverbankcomputing.com/Docs/PyQt4/html/qimagereader.html#supportedImageFormats

I see that svg is not part of that list. So, it is not surprising that
it does not work but there are plenty of other formats that will work.

It took me about 20 seconds to solve your problem by reading the
appropriate documentation. I suggest you do that too in the future...
