How does saying it's the cause of a problem help anything? I could ask the same question of you when you said "Another possibility to look for might be some wrongly configured IPv6 option somewhere, either on the laptop or the network".
The only thing that might be an issue is if IPv6 is enabled on the local network, but there is no IPv6 connection to the Internet. In that instance, a app might receive an AAAA record from the DNS and try to access the IPv6 address, even though it can't be reached.
This is common in Spain, and the OP is here now. I have this in "/etc/gai.conf": precedence ::ffff:0:0/96 100 and then my problems stopped. -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
