witray-hg segfaults when new applets are launched

[GoogleCodeExporter]

Background/Setup:
* I'm using ubuntu 11.10 on a 32-bit processor.
* I've compiled/installed libixp-hg r141 and wmii-hg r2809 (using gcc 4.4 and 
4.6)

Steps to reproduce the problem:
1. Login using wmii
2. Check that witray is not running ('cause it segfaulted)
  $ ps -ef | grep 'witray'
3. Launch witray
  $ witray &
4. Now launch nm-applet
  $ nm-applet &
Result: witray segfaults with: client_manager(0x1600003): Caught error.
5. Now with nm-applet still running, relaunch witray
  $ witray &
Result: You will see the notification icon in witray.  Everything will work, 
until another applet is launch.

I've tried this will other gnome applets and they all cause witray to segfault.
$ gnome-sound-applet

I'm guessing this has to due with some changes in gnome3.

Thanks for looking into this.  Also, thank you for working on such a great 
project.  Your work has greatly improved my day-to-day productivity.

That's not a segfault. Can you get me a stack trace? I don't 
have any such issues.

Can I assume that nm-applet has something to do with 
NetworkManager (people actually use that?)?

What do I have to tweak to include debugging symbols?

Otherwise the binary is stripped (I guess).

The default build configuration includes debugging symbols. If 
you're building a .deb, there's some debuild magic to get it not 
to strip, but it's best to just do an ordinary build and either 
install it to a temporary tree or just run the binary from the 
build tree.

Or you could install it normally and run 'make uninstall' when 
you're done.

Thanks for info (I've always been using deb target):

That's interesting. There's some other issue at play. Some X 
error is occurring when we're trying to swallow the window, 
though I can't imagine what it might be.
