UltraEdit crash on Fedora 16

Hi, I realize this may not be a bug in xfce but I could use some pointers on the issue so that I can redirect to the appropriate location|owner.  I provided UltraEdit's tech support a lot of info on this but I get the impression the only way something will get done is if I do a lot of the basic legwork.

Behavior:
UltraEdit 3.0.0.11 crashes when reorganizing [dragging from one location to another] the text editor tabs.

Output:
Gdk-ERROR **: The program 'uex' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 264782 error_code 3 request_code 18 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap

Relevant information:
1) I cannot reproduce the behavior using Gnome as the window manager
2) I cannot reproduce the error if I run with the --sync command line option
3) I can *only* reproduce the crash when  'Enable display compositing' option on the Compositor tab of Window Manager Tweaks is enabled.

It's because of #3 that I thought this may be a good place to post. I can provide all the usual nitty-gritty details about my environment, ldd, and full gdb output if anyone is interested but what I would appreciate initially is just some informed advice such as 'there is no way this is a xfce problem' or 'yeah, this could be a xfce problem'.

I don't want to overwhelm with info right off the bat but here are the first few stack frames from gdb:
(gdb) bt

Thanks in advance,

Re: UltraEdit crash on Fedora 16

After doing some additional research I found a bug in the wxwidgets trac site that looks like a winner: http://trac.wxwidgets.org/ticket/4841.

I'll update that ticket to see if I can get a pair of expert eyes to take a look.

Re: UltraEdit crash on Fedora 16

Can you check it your xfce4-panel (occasionally) crashes when D&D'ing window emblems in the workspace switcher? This seems similar to https://bugzilla.xfce.org/show_bug.cgi?id=8202
