Comment (by ncohen):
Ahahaahah... Stupid bug `:-)`
Ok, it is now fixed by the following patch. Here's what it does :
* It tests if the graph's complement is bipartite. Just a potential
speed improvement.
* Returns a result immediately if the girth is odd and > 3, and not
only if it is equal to 5
And ... more importantly `:-D`
* replaces an occurrence of ``self`` which should have been
``self_complement`` from the beginning `:-DDDDDDD`
