[igraph] python function for creating igraph_vector_t

[Pascal Jürgens]

Hi,

I'd like to use my own membership vectors (from Rosvall & Bergstrom's infomap 
algorithm) in the python interface. However, being a plain python list is not 
enough, as they don't seem to get converted. At least, passing them into 
contract_vertices crashes reliably (*).

Is there any way I can convert a list of int()s to some object that will hold 
the corresponding igraph_vector_t? Or am I on the wrong path and the underlying 
issue is something entirely different?

Regards,
Pascal Juergens

This is on a 0.6 build from yesterday, but also occurs on older ones:
python(5294) malloc: *** error for object 0x10582fa98: incorrect checksum for 
freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap
