[Pyobjc-dev] NSNetServiceBrowser misbehaving

[Bob I. <bo...@re...>]

I was just screwing around with Rendezvous stuff, and it seems to have 
found some kind of PyObjC bug..

When I run the attached program on the LAN for *some* services, I get a 
bus error with this backtrace:

(gdb) bt
#0  0x9068ba4c in objc_msgSend ()
#1  0x00246990 in pythonify_c_value (type=0xfe190 "@",

This traceback happens for _http._tcp (there should be a bunch of 
these) but not _daap._tcp (only my laptop is advertising right now).  
When browsing for _http._tcp I see the following output:
setDelegate

Bus error

I'm running the latest CVS of PyObjC and an Apr 26 CVS compiler of 
Python 2.1b1.
