Well I've had the same. Every time I get this error there is a 2nd default route to 0.0.0.0 in my route table (route -n). When I delete it (route del default) the error goes away. Installing the loopback seems to fix this also (probably updates the route table) but with me it works fine without.

Don't know for sure where this 2nd default route comes from but it looks as if the player has something to do with it (maybe in combination with synchronizing?).

In short, this is my "normal" routing table :

Kernel IP routing table
Destination_____Gateway________Genmask
10.10.0.0_______0.0.0.0_________255.255.0.0
0.0.0.0_________10.10.0.1_______0.0.0.0

And there's an extra
0.0.0.0_________0.0.0.0_________0.0.0.0

When this error occurs (as for the ___ : bbs eats my spaces).
