maybe you can get a better strace

I don't know if it's still valid but we have some info in the triage guide:

In reply to bug 5005 

Tested the new DVD ISO for Mageia 2 Beta 2 x86_64 ,and I have Several problems
in the MCC :

Mageia release 2 (Cauldron) for x86_64
Kernel 3.3.0-server-0.rc7.1.mga2 on a Dual-processor x86_64 / \l

1.When I want to Set up a new network interface ,I select Wired (Ethernet) and
I click on Next , and there the MCC crash.

# LC_ALL=C mcc

The program 'drakconnect' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 31254 error_code 3 request_code 153 minor_code 3)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

2.When I want to Set up the graphical server ,I choose an X server for my
Graphic Card (NVIDIA Geforce 6100 to Geforce 360) and then I click on OK ,and
there the same problem MCC crash.

The program 'XFdrake' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow'.

3.When I want to Set up boot system ,I add a new entry and then I click on
Finish ,and here again the MCC crash.

oxygen-gtk has been reverted to 1.2.1 and fixes that crash

CC: (none) => ennael1

Tested for the update oxygen-gtk 1.2.1 and for me the problem was not solved ,always the same crash.

did you update both oxygen-gtk and lib ?

I had this bug, too, and for me "down"dating both files to 1.2.1 fixed it

Fixed, thanks.

Status: NEW => RESOLVED
Resolution: (none) => FIXED

Ok, really sorry because I did not see the need downgrade version of package oxygen-gtk 1.2.2 to version 1.2.1-3.
I can confirm this downgrade fixed this bug.
Thanks.
