Crash with new Python API

[Janik Zikovsky]

If you have the new python API enabled by default, the following script crashes MantidPlot somewhere in the notifications of workspace replaced:

CreateMDWorkspace(Dimensions='3',Extents='0,10,0,10,0,10',Names='x,y,z',Units='m,m,m',SplitInto='5',MaxRecursionDepth='20',OutputWorkspace='mdw')
FakeMDEventData(InputWorkspace="mdw",  UniformParams="1e5")

This occurs if you fill in values in a pointy-clicky way as well. The same algorithms do not fail when run as C++ algorithms alonge (e.g. in unit tests)

... that fail because of it.

The stack trace for your enjoyment. It's going into the directory of the old PythonAPI which surprised me slightly.

This no longer crashes for me.

[Janik Zikovsky]

Confirmed working for me on Ubuntu 11.04 too.
