This might be fixed with http://git.gnome.org/browse/gnome-control-center/commit/?id=f33080ac1bfaec8e27c7d5315a2148af2ccca5ae

Pedro could you upstream this one?

The patch i've pointed previously is included in Gnome Control Center 3.1.91 can anybody reproduce it with that version? Last dup is with 3.1.90. Thanks.

Pedro,
I have the last version 3.1.91 of the gnome control center installed
and the problem remains...
I've also reported twice (one of them with the 3.1.91 version

Is there a way I could try something else?

Is the gnome control center on unity 2d the same? (I think I can't
reproduce this error with the 2d)

thank you,
José Luís

Jose Luis, is there any chance you might get us a backtrace with that version of g-c-c ? Please go to https://wiki.ubuntu.com/DebuggingProgramCrash to know how to enable the dbgsym repositories and then install gnome-control-center-dbgsym, libgnome-control-center1-dbgsym, libgtk-3-0-dbgsym and libglib2.0-0-dbgsym ; and run gnome-control-center inside gdb as:
gdb gnome-control-center
(when in gdb please execute:
set logging on g-c-c.txt
run
(reproduce the crash and)
thread apply all bt full
set logging off
quit
then please attach that resulting g-c-c.txt file to the report, Thanks in advance!.

Any news on this report? there's no report with 3.1.91, could anybody please follow the instructions i've posted previously and get a new trace with 3.1.91 ( or newer ) if its reproducible with it? Thanks.

With the latest upgrades, I could not reproduce this reported problem.

For me it seems to be solved,

Thank you.
