gnome-keyboard-applet crashed with SIGSEGV in gkbd_indicator_reinit_ui()

[Ken Arnold]

Binary package hint: gnome-applets

I resumed from hibernation this morning (first time after upgrading to the Intrepid alpha) to find this crash notice from the keyboard layout switcher, and my keyboard is back to just qwerty (was dvorak).

Upon reloading, now it just shows a question mark, and none of the layouts I had set up.

upstream comment:

"What is your XKB configuration? Is there any way to reproduce the crash without
going to hibernation?"

[Ken Arnold (kenneth-arnold)]

I have:
* USA Dvorak
* USA Dvorak international
* USA International (with dead keys)
* Arabic qwerty/digits

where the second one is default.

Here's gconftool -a /desktop/gnome/peripherals/keyboard/kbd:
 layouts = [us dvorak,us dvorak-intl,us intl,ara qwerty_digits]
 model =
 options = [grp grp:alts_toggle,grp grp:shift_caps_toggle,grp grp:sclk_toggle]

(those big spaces are actually tabs within an entry)

I'm going to try resetting to the default configuration.

I can reproduce this bug by plugging in a Apple USB keyboard into a docked ThinkPad X61 tablet.

gconftool -a /desktop/gnome/peripherals/keyboard/kbd
 layouts = [ch de_nodeadkeys,de nodeadkeys,us]
 model = evdev
 overrideSettings = true
 options = [eurosign eurosign:e,grp grp:sclk_toggle,grp_led grp_led:scroll,Compose key compose:caps,grp_led grp_led:caps,nbsp nbsp:level4]

[Ken Arnold (kenneth-arnold)]

After more aggregate experience, I can confirm that plugging in or unplugging an Apple USB keyboard seems to cause or aggravate the issue. Often the applet doesn't crash, but rather shows a default configuration (only one option: USA) and both builtin and external keyboards are left in qwerty. On occasion, unplugging the Apple keyboard actually makes the builtin keyboard return to Dvorak (!). (Or maybe the internal keyboard had just stayed in Dvorak and I hadn't noticed.)

This is all very strange. I could probably be of more help tracking this down if I knew how all the keyboard layout stuff worked. I haven't found much good documentation about it beyond xmodmap.

new upstream comment

"There is something in common. Whic is ... grp:sclk_toggle

Would the issue disappear if some other method of switching is used?

(I tried to reproduce it - no luck)."

[Ken Arnold (kenneth-arnold)]

Negative; I had reset to the defaults, which only had grp:alts_toggle. I
cleared even that; we'll see if I still get problems.
