The spatial reference object's resolution is undefined (NaN). Use one of the methods on ISpatialReferenceResolution to define a resolution value before calling SetMinimumXYTolerance.
Remarks
The SetMinimumXYTolerance method sets the tolerance to the value of the spatial reference's grid resolution (or 2.0 * XYResolution). Setting the XYTolerance using this method provides a mechanism to maintain backward compatibility with ArcGIS 9.1 geometric and relational operators. At version 9.1 and before, this is the only tolerance value used by geometric and relational operators.
