Thank you Nils
I looked at the tickets 
http://projects.scipy.org/scipy/scipy/ticket/301 <http://projects.scipy.org/scipy/scipy/ticket/301> 

http://projects.scipy.org/scipy/scipy/ticket/387 <http://projects.scipy.org/scipy/scipy/ticket/387> 

It seems that inded, there are some serious bugs in  Bessel and Kelvin functions in 'special' package.
However, the bugs reported in these "tickets" are not the bug I encountered. 
Perhaps they are related.
