Issues with Quickly: tk-WARNING **: Unable to locate theme engine in module_path: "pixmap" [duplicate]

Gdk Gtk warnings and errors from the command line

I'm fairly new to Ubuntu, and I decided that I want to learn to develop applications for it. I found some great tutorials, and installed Quickly and started to play around with app development. For some reason though, when I typed in "Quickly create ubuntu-application hello-world" like the tutorial said, the terminal window said the normal "Creating project directory hello-world Creating bzr repository and committing Launching your newly created project!" But then said (hello-world:23506): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(hello-world:23506): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(hello-world:23506): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(hello-world:23506): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

The "hello world" application launched seemingly fine after that, but is it a problem? If so, how can I eliminate it? I'm on Ubuntu 11.10.

Solution 1:

It's a fairly low level error but you should be able to fix this with installing it...

From command line

sudo apt-get install gtk2-engines-pixbuf

or click the icon here: gtk2-engines-pixbuf

Found the solution on Launchpad.
