Bug Description

Binary package hint: gnome-system-tools

users-admin when clicked used to just not show up in Gnome 3 but I noticed that recently there were some updates to it so I thought I'd try it again. I've been able to work around the problem but it would be nice to have the tool available.

users-admin isn't part of the stock GNOME3 experience, but it should work if you still need it rather than the new users control panel.

The crash here comes from a bad packaging/build that mixes GTK2 and GTK3 symbols:
#2 0x00007f87f66eca22 in g_logv (log_domain=0x7f87f95c779b "Gtk", log_level=<value optimized out>, format=0x7f87f9659d88 "GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported", args1=0x7fff2b3ab690) at /build/buildd/glib2.0-2.28.6/./glib/gmessages.c:557

So that's not a crash per se, rather a broken package.

users-admin 2.32 is supposed to use GTK2 only, while users-admin 3.0 uses GTK3 only. When you speak of GNOME3, do you mean you installed it from the PPA?

I did install gnome 3 from PPA (
gnome-system-tools is version 2.32.0-0ubuntu7. I did not find any newer package.

That's most likely a GNOME3 PPA bug then.

Apport retracing service has marked bug 819821, which is *not* a GNOME3 PPA bug (c.f. similar bug 814060 which is also not a GNOME3 PPA bug), as a duplicate of this bug (and removed all the useful attachments). Should I reverse that operation and manually attach a stack trace to bug 819821? Or should this bug be elevated to High (like bug 814060) and no longer considered a GNOME3 PPA bug?

gnome-system-tools is deprecated in gnome3.
Derivatives which still use it need to either fix it to make it work with gtk3 or use equivalent gtk3 based tools.

I find at least 1 package which use GTK3 and linked to this : libpolkit-gtk-1-0. policykit-1-gnome needs to provide a package of the library build against GTK2 if we want to fix it.

polkit-gtk shouldn't link to GTK3, but to GTK2: polkit-gtk isn't needed by GTK3 programs, since they have to use GtkLockButton to replace PolkitLockButton. Linking to GTK2 is still the upstream default actually.

If gnome-system-tools is deprecated in Gnome3, is the gnome2 package available? We did have this in 11.04. Is it possible to simply pin the package for 11.10?

Ok, if gnome-system-tools is deprecated in Gnome3, what about Xfce, means Xubuntu?

It seems they still use and need this package. I realized this bug, while using Xubuntu@Xfce (pls. see Bug #824485) ...

As gnome-system-tools is obsolete and replaced with accountsservice/gnome-control-center, I downgrade this to Medium. It is not a release critical bug.

@pitti: Are you sure that all flavours of Ubuntu (Ubuntu, Kubuntu, Xubuntu and Lubuntu) include the new accountsservice/gnome-control-center in Oneiric? Would their doing so noticeably increase disk or memory footprint by requiring other depedencies also be installed by default?

If in fact any of the official-but-non-default flavours of Ubuntu still need to use gnome-system-tools, then I submit that this *is* in fact a release critical bug for those flavours and should be accorded appropriately high priority and upgraded back to High.

OK, fair enough. This got assigned to the desktop team, but please anyone feel free to grab this bug.

I confirm that rebuilding policykit-1-gnome with GTK2 fix the problem. Also, the rdepends are only using GTK2 also, so it's should be safe to switch to GTK2 :

I'll prepare a merge proposal.
