SIGSEGV when resetting "Open in Terminal" keyboard accelerator

[Daniel Gnoutcheff]

Binary package hint: nautilus

I have the nautilus-open-terminal extension installed. I have '/desktop/gnome/interface/can_change_accels' set to true, which allows me to set keyboard accelerators by pressing a key while hovering over a menu item. (I originally enabled this from gnome-appearance-properties; in karmic, there was a checkbox for this option. It has now been removed.) In this way, I bound the "Ctrl+`" accelerator to the "File -> Open in Terminal" menu item.

Most of the time, this works as I expected: "Ctrl+`" shows up as the accelerator for "Open in Terminal" in the menu, and pressing Ctrl+` opens a terminal in the currently displayed directory (very handy).

However, after nautilus has been working for a while, it sometimes "loses" this this accelerator. Then, Ctrl+` fails to do anything, and nautilus claims that the accelerator for "Open in Terminal" is "-/-". When I try to reset it (by hovering over "File -> Open in Terminal" and pressing Ctrl+` again), I get the segfault captured in this apport report.
