freeze-vim-setting

Environment

OS : Debian sid
Version of Vim : 7.3
For more detail, see .vimrc & bugreport.txt.

How freeze

When I use omnifunc(=rubycomplete#Complete) in ruby file, display the search message and never finish searching.
(I think, omnifunc should return some suggestion or "Pattern not found".)

How reproduce

This is a example of the file for reproduceing freeze.
```
foo = gets.bar  
foo.(type <C-x> <C-o>)
```
For more exampe, see test.rb file.
