nm-applet crashes with SIGSEGV

Test environment: Ubuntu 7.10 + latest updates
Date of test: Oct 26 2007
Desktop environment: GNOME
ProblemType: Crash
Architecture: amd64
ExecutablePath: /usr/sbin/nm-applet
Package: network-manager-gnome 0.6.5-0ubuntu10
PackageArchitecture: amd64

I am using a Lenovo T61 laptop and nm-applet crashes pretty consistently when I left-click the icon in system tray and then click 'Connect to Other Wireless Network...'. I compiled a debug version of nm-applet and backtrace showed that it crashed when calling a function in gtk+ library. Then I compiled a debug version of gtk+ libraries and get the backtrace as attached.

Another thing to note is that I found there is a 'gtk+2.0-2.12.0/debian/patches' dir in the source package I got by 'apt-get source'. I also compiled another version of gtk+ libraries without applying those additional patches in the 'gtk+2.0-2.12.0/debian/patches' dir and crashes of nm-applet never happen again.

Yet another thing to note is that it seems crashes do not happen either when running nm-applet under the contorl of Valgrind. I tried at least 30+ times and did not see any crash.
