wireshark attempting to retrieve a large itnerface list from rpcapd

Build Information:
Version 1.2.0pre2 (SVN Rev 28667)
--
Version of wireshark: Version 1.2.0pre2 (SVN Rev 28667), running on
Windows XP, SP3

rpcapd from is from:
http://www.pawelko.net/linux/17-Rpcapd-For-Linux-Remote-Sniffing-With-Etherealwireshark

rpcapd running on an ethernet switch: Arista DCS-7148S:
http://www.aristanetworks.com/en/7100_Series_SFPSwitches

The switch runs linux (2.6.29.1) and has 48 10G interfaces plus a couple
of management interfaces.  'ifconfig -a' lists 52 interfaces.

When Wireshark attempts to get the interface list from the remote host,
it crashes.

By taking certain actions on the switch, I can prevent the switching ports from
showing up in the interface list, so ifconfig only lists the 2 management ports
+ the loopback.  In that case, Wireshark can successfully retrieve these
interfaces and capture as expected.  Its only when rpcapd returns 52 interfaces
that Wireshark crashes.  A capture the rpcap communication (Remote Packet
Capture, Find all interfaces request) that causes the problem is attached.

Thank you.
