Sounds simple enough, however i'm not clear on how i set the values
>>> igraph.arpack_options.iter
3000
>>> igraph.arpack_options.iter=5000
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: iter

Eigenvector calculations in igraph 0.4.5 were not based on ARPACK, so
that's the cause why there's no warning in 0.4.5. I can't judge
whether the result of 0.4.5 is correct or the result of 0.5; but maybe
raising the maximum number of iterations allowed in the ARPACK module
will help. The Python interface has a variable called arpack_options,
which is an instance of class ARPACKOptions (see
help(arpack_options)). arpack_option has an attribute called maxiter
(which is 3000 per default) that can be modified to allow more
iterations. Maybe this helps, maybe not.
