Crash on Edit Profile

Looks like this has been going on for quite some time now. (2007)
https://bugs.launchpad.net/ubuntu/+source/sabayon/+bug/150068

+1 (Linux school 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux)

My symptoms are exactly the same as Ryan's If this were a commercial project, This bug would be a sev1 - stop ship. How comes it's languishing unassigned.
(I'm not a coder, or I'd offer to help out ;o)

Someone please fix this as I urgently need it to set up a pre-school PC (Natty/Edubuntu/Unity) so that pre-school kids are ONLY able to run the programs appropriate for their age/capability and NOTHING else. The reason I suggested Linux over their existing XP setup is because I thought it handled exactly this use case. I presume Sabayon is able to achieve this in Unity?

Cheers, (and thanks for your anticipated urgent attention)

(I did add myself to the 'also affects' link but wanted to add comments too)

I have a fix, edit line 276 in /usr/lib/pymodules/python2.7/sabayon/protosession.py

Change the h's to i's so it looks like this
pack_format = ">ii%dsi%dsi%dsi%d" % (display_addr_len, display_num_len, xauth_name_len, xauth_data_len)

It will then work. Hopefully someone can patch this.

Actually H (capital) is more correct than i. H is an unsigned short.

Check out /usr/include/X11/Xauth.h

typedef struct xauth {
    unsigned short family;
    unsigned short address_length;
    char *address;
    unsigned short number_length;
    char *number;
    unsigned short name_length;
    char *name;
    unsigned short data_length;
    char *data;
} Xauth;

It should be an unsigned short (H) instead of just a short (h). Int (i) happens to work as well but unsigned short is more correct.

For those who just want sabayon to work do
sudo nano +276 /usr/lib/pymodules/python2.7/sabayon/protosession.py
and make the h's into H's so it looks like
pack_format = ">HH%dsH%dsH%dsH%d" % (display_addr_len, display_num_len, xauth_name_len, xauth_data_len)

With Maverick Meerkat 10.10 I am still getting this error. Sabayon 2.30
apt-cache policy sabayon

Also, even after applying the above patch I get this error:

11.10 doesn't run even with my fix. Are we just giving up on sabayon? It's very important to anyone managing Linux desktops.

I'm trying to figure out how to make it work. sessionwindow.py line 82 loads an image that apparently no longer exists in gnome 3.2. I changed "stock_lock-open" to "stock_lock" to get around.

Now I get

I am running Ubuntu 10.04 (a basic install) I discovered something interesting in troubleshooting this problem with Sabayon. It fixed the problem for me. I noticed that the resolution was set to 800x600 on the server which seemed low to me, so I bumped it up to 1024x768 and the Sabayon problem went away. Before, I would create a profile and when I clicked on the edit button Sabayon would crash. Now after bumping up the resolution, when I create a profile and click on edit...the virtual desktop of the profile loads just fine. i figured this out because I had another server running the exact same version of Sabayon and Ubuntu and everything worked just fine.

I know this is a really old thread, but I thought I would throw that out there for those of us who like the Sabayon features.

Thank you for taking the time to report this bug and trying to help make Ubuntu better. However, this package is no longer part of Ubuntu repositories. Because of this the Ubuntu project can not support or fix your particular bug. Please report this bug to the provider of the software package. Thanks!
