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.
It's a fairly low level error but you should be able to fix this with installing it...
From command line
or click the icon here: gtk2-engines-pixbuf
Found the solution on Launchpad.
