Problem with workspace history in workspaces loaded from file

[mantid-builder]

Original Reporter: Steve Williams

There is a problem loading or saving array properties in workspace histories to file.
The resultant workspace from this script has a bad history

Load(Filename="C:/mantid/Test/Data/MAR11001.raw",OutputWorkspace="test")
Rebin(InputWorkspace="test",OutputWorkspace="test",Params="0,10,20000")
SaveNexus('test', 'C:/mantid/delete.nxs')
Load('C:/mantid/delete.nxs', 'badhistory')

Right click on the workspace "badhistory" and select "Show History" the Rebin() command's last argument has been trucated. The workspace history of "test" is correct.
