Vim 7.3 on Windows -- Installed Successfully But Crashes When Opening A File

I am on win7 with vim 7.3. I installed rubyinstaller-1.9.1-p430 and DevKit-4.5.0-20100819-1536-sfx, so that (I think) the version of ruby vim came compiled with matches the one I used to execute ruby extconf.rb.

Here is the output of the make command:

gcc -I. -IC:/Ruby191/include/ruby-1.9.1/i386-mingw32 -I/C/Ruby191/include/ruby-1

At first I was happy because it seemed to be working: http://i.imgur.com/hxQ4S.png

But then I was sad because as soon as I selected a file by pressing enter, vim crashed: http://i.imgur.com/sft8b.png

Any ideas for troubleshooting?
