I have downloaded and installed a new theme before in my fedora machine.

However, I got this warning when I load gvim, nautilus every time.

(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "equinox",

How can I download this theme engine?? and remove this warning?

Install gtk-engines package from your distro's repository. If there's not a gtk-engines package, search for a package with a similar name, you shall find one.

For ubuntu the package name is gtk2-engines. You may need to reinstall the package:

$ sudo apt-get install --reinstall gtk2-engines

I am using fedora, how can i Download that from distro? I am a linux new bie :( –  Kit Ho Sep 20 '11 at 13:46
AFAIR, Fedora uses Yum to get packages, if so, try running "yum install gtk-engines" from your terminal. –  MilanorTSW Sep 20 '11 at 14:40
Alternatively, try downloading an rpm package for your architecture from here: fr2.rpmfind.net/linux/rpm2html/search.php?query=gtk-engines and install it using "rpm -i <package-name>". –  MilanorTSW Sep 20 '11 at 14:47

If it's unable to find the engine, it means you haven't installed them yet. Simply do someting like this:

sudo yum install gtk2-engines gtk-murrine-engine gtk-equinox-engine

this is a correcter answer as the other one doesn't say anything about the murrine or equinox engine –  DarkMukke Jan 26 '13 at 10:19
Packages are named gtk2-engines-murrine and gtk2-engines-equinox for some distributions. –  Wallacoloo Apr 3 '13 at 21:53
it is "gtk2-engines-murrine" in ubuntu. Perhaps you should also consider installing "murrine-themes" –  Hongbo Zhu Dec 9 '13 at 9:16

People experiencing this problem with, eg Acrobat Reader on 64bit installs should try this:

sudo apt-get install gkt2-murrine-engine:i386

could u elaborate Usage of gkt2murrine engine? –  BlueBerry - vignesh4303 Aug 30 '13 at 7:58
I've no idea what it does under the hood, just that Acrobat Reader complains if it's missing, and doesn't if it's present. There are accounts of problems with older versions of vmware-player requiring gtk2-murrine-engine as well. –  John Morton Sep 1 '13 at 2:15

On Ubuntu 13.10 the command i needed was:

sudo apt-get install gtk2-engines-murrine:i386

I know the question is about fedora but I ended up here where one of the answers pointed me in the right direction.

Just in case it would be helpful to others.
