using the 32bit official linux binary build of bitcoin, on ubuntu lucid 32bit. when there are no network interfaces up (i.e., network cable disconnected), bitcoin client fails to start with a segfault. no such issue when a network cable is connected and an interface is up. no such issue when an interface is up, but firewall blocks all incoming and outgoing packets. if bitcoin is started, then network cable is unplugged, bitcoin hard crashes. issue does not occur with previous release, 0.3.22.
gdb traceback of the segfault included below:

if you need further information, please ask. but otherwise, should be able to confirm this with (i think) any 32bit linux. or if not, then least, 32bit ubuntu lucid. :)
