plugin for XFCE panel crashes suddenly

[GoogleCodeExporter]

Zenwalk-snapshot, XFCE4.

GlobalMenu plugin suddenly disappears from the panel so that i have to
place a new one. It s an autohiding panel 20px width at the top of the screen.
It happens while i'm doing something with windows - opening/closing file
mnager or some other programs, i haven't figured out which programs exactly.

In .xsession-errors i'm getting this:
--------------------------------------
.....lots of debug output....

   backtrace from your debugger if you break on the gdk_x_error() function.)

The last message sais that "the element has been suddenly removed:
GlobalMenu module for XFCE"

Placing it here in case someone can take it over.

It happens also when the panel is not autohiding.

Here's the same output with --sync enabled.

It happens most reliably for me at dialog close, for example the save dialog of 
GIMP.

Same thing is happening here. I'm running Arch Linux with Openbox and 
xfce4-panel.

[The Error]

The program 'GlobalMenu.XFCEPlugin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadDrawable (invalid Pixmap or Window parameter)'.
