lxpanel crashed with SIGSEGV in g_main_context_dispatch()

Binary package hint: lxpanel

Lxpanel crashed after Firefox 3.6.9 locked up and was closed.

Description: Ubuntu maverick (development branch)
Release: 10.10

lxpanel 0.5.6-0ubuntu1

What I expected:
Firefox to close.

What happened:
Panel was in autohide mode. I moved cursor to panel area and panel did not respond. A message popped up asking me if I wanted to end the application. I clicked "yes" and Firefox closed. Immediately I received another pop-up informing me that Lxpanel had crashed. The panel the re-opened and I responded to the message with this report.
