[pymvpa] one class again

I have questions regarding the one-class svm implementation:
when training on a dataset of small size (where there might not be any
structure) the call to train often hangs forever.
When I create a random dataset with the same dimensions, or if I replace
the content of the sample array with random, it runs smoothly.
I checked in my dataset and there are no nans or infs.
Could this be just the distribution of the data that causes this to hang?
I know that this problem is due to LibSVM but I wanted to confirm that it
is the last version that is included in PyMVPA.
