[CIG-SHORT] I/O error while reading SimpleDB data.

[Brad Aagaard]

Yes, you can create a linear variation in the axial load. You need to 
add a line feed at the end of the file. See 
http://www.geodynamics.org/cig/community/workinggroups/short/workarea/pylith-wiki/index_html#errors_spatialdata

I have made the error message more verbose to suggest the proper fixes. 
This will appear in the next release.
