Solver - Error Creating Marker Deviation AnimCurves

[david-cattermole]

Problem

Sometimes an error is returned after solving. The reproduction steps are unknown, but the traceback is helpful.

Expected behavior: No error should occur.

Actual behavior: Script Editor error:

ERROR: [maya] in method 'MDoubleArray_append', argument 2 of type 'double'
