[ome-users] Plot line error

[Philippe Mailly]

Hi,

The plot line functionality don't work in the web interface. I got the 
error message in the web log:

AttributeError: 'module' object has no attribute 'isNumberType'

The OMERO server 4.4.8 run under Ubuntu 13.04 and python math libraries 
are installed. And I have no problem with the Insight module.
