Okay, good to know. Thanks.

Yes, that's it. Good call.
I can now reproduce the problem by running this simple C program.
Compile with
gcc a.c -lXaw
Then a.out will reproduce the problem. I can actually do this in a
session with just an xterm. I don't even need a window manager.
I have also determined that the rdesktop client is exiting because it is
receiving an appid == MCS_DPUM (Disconnect Provider Ultimatum). This is
happening in mcs.c line 364 (from the pristine 1.6.0 sources), which I
determined by running rdesktop in a debugger. So altering the cut
buffer is causing xrdp to send a disconnect, or at least to send
something that looks like a disconnect to rdesktop and also to mstsc.
You're not seeing that? I wonder what it could be.
