WINEDEBUG="+all,-relay" near dialog-generating location

LPE gets stuck in a loop trying to download updated files and re-launch.  A
dialog appears (.NET 2.0?) that says (at the beginning of the loop):
Main: Unable to read data from the transport connection: Unknown error
(0x271e).
Address: http://lpe.ocdsoft.com/installer/LaunchpadEnhanced.exe
File:C:\Program Files\Launchpad Enhanced\LaunchpadEnhanced.exe.temp

The error appears to be from passing an invalid memory location to WSARecvFrom
after the original buffer runs out (see abbreviated log attached).  Note that
the messages:
0009:trace:winsock:WS2_recv recvmsg sta: (ptr) (ptr) (length)
are from adding a trace to output hdr.msg_iov, hdr.msg_iov->iov_base, and
hdr.msg_iov->iov_len. This message was added to explore why the errno was being
set to 14 (EFAULT), which the recvmsg man page indicates is due to a pointer
being outside the application address space.

The issue might be some form of regression (since LPE worked on Wine 1.0-rc2),
but since the application has an automatic updater it's possible that the
application code changed.
