segfault with DMX

Hi,
We're trying to get DMX running properly on a 3 width 4 high (3x4)
array of monitors.  Each column  of 4 is driven from a single computer
and is running xinerama.  We are running  dmx-1-2-20040630 .  We tried
both the Debian package and a hand copmiled version.  Our Debian
system is 2.6-15 with Xlibs 6.9.

We are able to get terminal and sawfish running, but when we resize
the window, DMX crashes and we're left with a segfault error.  This
even happens on a 1x1 window test case.  if the window is moved just a
bit, nothing crashes.  when it's moved above a vertain threshold, dmx
crashes.

The servers are running Ubuntu with Xlibs 6.8.
here's the backtrace;

Program received signal SIGSEGV, Segmentation fault.
0x08167d38 in miCompositeRects ()

any ideas/

thanks,
