[Pkg-utopia-maintainers] Bug#690270: network-manager-gnome: segfault when hitting tab in nm-connection-editor's IPv4 settings window when GTK_IM_MODULE=xim

Package: network-manager-gnome
Version: 0.9.4.1-2
Severity: normal

from a posix shell, run:

  GTK_IM_MODULE=xim nm-connection-editor

On the "Wired" tab, click "Add"

In the new dialog box, click over to the "IPv4 Settings" tab.

Change the method to "Manual".

Click the "Add" button.

Press the tab key on your keyboard.

I get a segfault with this backtrace:

Program received signal SIGSEGV, Segmentation fault.
