Failed to load pixbuf file

[tianum]

I have installed salix core.
then all packages x
# slapt-get --install-set x
the window manager jwm
# slapt-src -i jwm
and gslapt
# slapt-get -i gslapt

When execute gslapt, the icons for state of each package are not loaded
and this message in the console:

Code: Select all

(gslapt:22991): Glib-GObject-CRITICAL *: g_object_unref: assertion G_IS_OBJECT (object) failed
Failed to load pixbuf file: /usr/share/gslapt/pixmaps/pkg_action_installed.png: Impossible de reconnaitre le format d'image du fichier </usr/share/gslapt/pixmaps/pkg_action_installed.png>

The package gdk-pibuf is installed. Perhaps, another package is missing, but which one ?
Thank

Perhaps libpng

Run

Code: Select all

as root.

I make an alternative by doing basic installation with xfce, and it is a better solution because the disk space is 2 GB instead of 3,2 GB (install on an old laptop with a small hard drive)
The problem has disappeared, and it only remains to replace xfce and install my favorites software
Thank you for your help.
