[CIG-SHORT] pylith error

The error message you are getting when the mesh is imported is associated with 
a bug in the partitioning (that has been fixed in the development version). 
This is not associated with the real error you are getting with the slip 
spatial database. The spatial database relies on interpolation to set the 
slip values. As a result, it will spit out the error message you are getting 
when it thinks it has to extrapolate. Double check to make sure the number of 
points and topology of the spatial distribution match the actual 
distribution. A 1-D topology must be a line, a 2-D topology must be a plane, 
and a 3-D topology must be a volume.
