Description of problem:
When installing 'vim-command-t' via yum, the installation errors:
Non-fatal POSTIN scriptlet failure in rpm package vim-command-t-1.4-1.fc17.x86_64                                             


Version-Release number of selected component (if applicable):
0:1.4-1.fc17

How reproducible:
I've done this on 2 workstations so far; same error both times.


Steps to Reproduce:
1. Install from f17 Live CD on a VM; update && reboot
2. Upgrade VIM: $ sudo yum -y install vim-common vim-enhanced
3. Install Command-T: $ sudo yum -y install vim-command-t

Complete!

Leaving the package installed causes vim to fail:
$ vim
Vim: Caught deadly signal SEGV
Vim: Finished.
Segmentation fault (core dumped)


Expected results:
vim-command-t installs correctly and without error.


Additional info:
I suspect this would happen on non x86_64 arch's as well but I have not tested that.

Also, asked someone in the fedora IRC channel to duplicate this for me. They received the erorr "after I get a segfault".


Work-around: 
Clone command-t from GitHub (vimball did not work for me on a new install)
https://github.com/wincent/Command-T
Follow directions to install.
