RE: [Discuss-gnuradio] blks2.synthesis_filterbank

So, interesting things.  Incidentally, I was the guy who posted about the 
segfault in top_block.

1) On my laptop runing ubuntu 7.10 natively with latest stuff installed, I got 
the segfault.  On my virtualized ubuntu on my macbook, I got a real error 
message (btw & fyi, ubuntu + parallels does not work with the USRP).  
2) The error message that I got as that was segfaulting the native ubuntu was 
the same error message I was getting for the blks2.synthesis_filterbank:

"insufficient connected output ports (2 needed, 1 connected)"

The difference is that I'm getting the error because of my C++ block (either 
because of the C++ code, or how it was connected in the python).

It might be the case that if I fix my own code, I can also fix the 
blks2.synthesis_filterbank.

Cheers,

-Ben
