[mythtv-users] Mac OS frontend can't 'ping' backend - 'Interrupted system call'

Hello,

I'm having some troubles with a Mac OS frontend. The gui complains about
being unable to 'ping' the backend, and as a result goes around in a
loop asking me to select a backend.

Looking at the console I see:

And so on. So it looks like myth is having trouble successfully
executing the ping test. If I run that ping command manually, I get:

pvr2:~/myth/MythFrontend.app/Contents/MacOS pvr2$ ping -t 3 -c 1
192.168.90.5
PING 192.168.90.5 (192.168.90.5): 56 data bytes
64 bytes from 192.168.90.5: icmp_seq=0 ttl=64 time=0.369 ms

--- 192.168.90.5 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.369/0.369/0.369/0.000 ms
pvr2:~/myth/MythFrontend.app/Contents/MacOS pvr2$

So obviously the frontend can ping the backend. Also, other (non OSX
frontends) connect fine.
This is using SVN trunk from last night and QT 4.3.4.

Any thoughts as to how I could fix this problem? 

Cheers,
-Kent
