Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", at /usr/share/perl5/Debconf/FrontEnd/Gnome.pm line 111.

[Thomas]

mostly when I install a package I get this message:

Gtk-WARNING **: Im Modulpfad »pixmap« konnte keine Themen-Engine gefunden werden, at /usr/share/perl5/Debconf/FrontEnd/Gnome.pm line 111
Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap", at /usr/share/perl5/Debconf/FrontEnd/Gnome.pm line 111.

it looks like there is something missed?

it looks that gtk2-engines-pixbuf is not installed by default. after installing this package (together with gnome-themes error is gone.

The bug is the missing installation.

I didn't notice this bug until I upgraded my Ubuntu test partition to 12.04.

My bug reports the problems occurring at lines 97 and 103 of the appended file.

[Christopher (soft-kristal)]

I have the Gtk2-engines-pixbuf:i386 installed on my 64 bit system, and when I try to install the non-i386 PP version I get an error.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Andreas Gubner (agubner)]

Today I installed Gnuplot on Ubuntu 11.10 (64-bit) and had a quite similar problem when trying the installation by plotting sin(x):

Solution that worked for me was posted by Bernhard Kleine (Post #4), thanks a lot, Bernhard:

Similar-- Do a fresh install of 12.04 and go on to do the updates of packages which total 647 packages-- throughout the process I get the pixmap errors similar to this (they change a little but you get it off and on throughout the upgrade process.

Fix released in Ubuntu 12.04 precise since new version of light-themes (0.18.32-0ubuntu2) now depends on gtk2-engines-pixbuf.
