gnome-settings-daemon crashed with SIGSEGV in g_return_if_fail_warning()

[Alex Popovskiy]

Binary package hint: gnome-settings-daemon

gnome-settings-daemon causes high CPU load after swithcing keyboard layouts several times, and then keyboard just goes crazy - layouts switched randomly and layout indicator (scroll lock) blinks very fast. It can be stoped only by gnome-settings-daemon restart.

Thank you for your bug report, could you check if that's still an issue after upgrading to the current version and restarting your session?

[Alex Popovskiy (alex-popovskiy)]

It still happens on a system that was updated just yesterday.

[SAVEL (nofuture-mail)]

The bug is still there at the moment...

[Mike A. Kuznetsov (mike4gg)]

This bug really makes me cry. Please, fix it for release

[Screatch (screatch)]

Affects me aswell.
Will do a clean install of RC and see if this will be solved.

[Yura Tolstik (yltsrc)]

I am crying every day for few month yet, but nobody cares as i see :(

[Marat Dyatko (marat-dyatko)]

Yura, I'm too!

And I feel lucky to get everyday challenge in typing "top" and "kill ####" in terminal.
Layouts switching very fast and I'm trying to catch every English letter.

It's so crazy cool, guys!
Please leave that bug as feature in the new 10.10 release!!!!

[Dmitry Shachnev (mitya57)]

Still present. After an hour of normal work, layout starts to switch
uncontrolable (USA <> RUS). Keyboard indicator always displays USA, I
can't change it.
For example, if I type 'qwerty', i get 'qцуrен'
It's of course a very important bug.

//Is it *only GSettingsDaemon* issue?

[Anton Voloshin (zombieff)]

You can also kill (or remove from gnome-panel) the indicator-applet to stop layout switching. Then run (or add) it again.

May it be that the issue is caused by indicator-applet?
