Hmm, I think you found the problem of bug 1377:

http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1377

Having a quick look, though, I am a bit confused because it doesn't 
appear anybody ever allocates any space for 'err_str' before calling 
though maybe I'm missing it.  Anyway I don't really have time to dig 
further for the moment.

Another thing that needs a look is it appears that it's normal that 
AirPcap is compiled in (I didn't change my setup and my Windoze builds 
say "with Airpcap") though in that case I'm not sure it should be 
complaining at all if it doesn't find an AirPcap device or whatever.
