I can confirm this bug too: mate 1.6 from official rep on debian wheezy. Here is what I did:

  $ dconf dump /org/mate/desktop/keybindings/ > test
  $ cat test 

  [custom0]
  action='/usr/bin/firefox'
  binding='<Shift><Mod4>f'
  name='Firefox'

 # add another keyboad short cut with your favorite editor (vim or pluma)
  [custom1]
  action='/usr/bin/firefox'
  binding='<Shift><Mod4>g'
  name='Firefox2'

 $  dconf load /org/mate/desktop/keybindings/ < test
 # try to start       

 $ mate-keybinding-properties 
  Segmentation fault

Erasing ~/.config/dconf/user enables the start mate-keybinding-properties again.

[CopyKat]

Confirm. Arch Linux, mate 1.6 from official repo.

@sbalneav This can be closed?

Nothing else heard, closing.

I don't believe this can be closed yet. It's an issue for me on Debian Wheezy i386 with MATE 1.8 from wheezy-backports, and it has been since I used 1.6 from the MATE repo.
Here's the GDB output, but I'm sorry, I don't know how to interpret GDB.

@stephenangelico As per commit ea467b2 , this bug has been fixed in the mate-control-center 1.8.11.6.1 release, if your mate-control-center package is older than 1.8.1 upgrade it should fix this issue.

[infirit]

@stephenangelico Here is how to get a proper backtrace in debian, https://wiki.debian.org/HowToGetABacktrace.

If you, as @Vdragon said, have version 1.8.1 and can reproduce this do post the backtrace here. But please make sure to enclose them in ``` (3 backticks).

[stephenangelico]

Yeah, I've got 1.8.1:

$ apt-cache policy mate-control-center
mate-control-center:
  Installed: 1.8.1+dfsg1-3~bpo70+1
  Candidate: 1.8.1+dfsg1-3~bpo70+1
  Version table:
 *** 1.8.1+dfsg1-3~bpo70+1 0
        100 http://ftp.iinet.net.au/debian/debian/ wheezy-backports/main i386 Packages
        100 /var/lib/dpkg/status

I also got different output from GDB. I also got libc6-dbg and libgtk2.0-0-dbg (as you can see from my above comment, I already got mate-control-center-dbg). Thanks @infirit for the link on Debian backtracing. This is the result, but I'm still missing a file:

I haven't mentioned that this only happens on my i386 laptop. My desktop, also running Debian 7.5 with MATE 1.8, but amd64, doesn't have this problem.

[Vdragon]

@infirit @stephenangelico I've made a mistake, the fix of this issue should be landed in 1.6.1 instead of 1.8.1 , so it's a strange situation now.

And I confirmed that similar issue happened in version 1.8.0 as well on my Ubuntu 14.04 32-bit machine, I'll add my backtrace when I found time switch to MATE DE.

[infirit]

It fails in the same function as far as I can see so re-opening.
