Bug #1826: Segmentation fault when using command-t

I get a segmentation fault when using command-t. I can switch to a file maybe once, but the second time I open the command-t window I get a segmentation fault after typing a few characters.

I might add that I haven't used this computer in a while and at some point command-T started having problems on it. I am not sure if it was after I dist-upgraded ubuntu to 11.04 or if I accidentally pressed some odd modifier + key-combo when using command-T. I tried wiping my .vim/ruby/command-t folder and then sourcing the latest (command-t-1.2.1.vba) vimball to try to do a re-install of command-T to get it working again. The problems I had been having involved some weird Zero Count errors when running command-T's functions. The result of this was that I could never close the command-T window and had to stop the process and kill vim instead to get out.
