Layer symbology does not update in TOC when using categorised style

Add a vector layer to the project (I'm using a point shp), open style properties, choose categorized style, select field to use, click classify. Table is populated with selected symbol styles and colours. Clicking OK without first clicking Apply does not update the symbology of the layer in the TOC until the layer position in the TOC is changed. The same is true going from a categorized layer to a layer with a single symbol - TOC is not updated if Apply is not clicked before OK.

Setting the categorized style and clicking Apply and then OK correctly updates the symbology in the TOC.

I'm using QGIS master ca6d4d9 on Windows 7 32 bit.

Closing QGIS and restarting stops the problem for a while and then it starts happening again. I have attached a screenshot showing the new style on the canvas (pink dots) and the old style in the TOC (green dots). If I move the layer in the tree then the symbol updates.
I have attached a screenshot and some output from DebugView when I changed the colour from pink to orange.
