Comment:

 You mention in the mail
 http://permalink.gmane.org/gmane.comp.python.scientific.user/29206 that
 the same issue arises with a separate Matlab implementation of LOBPCG.
 This seems to point out that the issue is a limitation of the algorithm
 itself rather than a bug in Scipy's implementation. So, it seems unlikely
 this is a bug that can be fixed.
