[Tom Goddard]

Setting html for the file history Qt html widget crashed. It was updating after a new data file was opened. The html contains inline encoded images so can be large although it is known to truncate the html if more than 1 or 2 Mbytes in size, so our code switches to loading the html from a file in that case. In this crash it was directly setting the html because the size was less than 1000000 bytes.

Seems like a Qt bug.
