autoclose.vim E444 cannot close last window

[Fernando Basso]

Error detected while processing function <SNR>19_CloseStackPop:
line 3
E444: Cannot close last window.

That is the full error. It happens when autoclose.vim is enabled/loaded
and I am in insert mode and hit <Esc> or CTRL+[. It doesn't matter what
is the current filetype, the problem persists.

Vim 7.3 Included patches 1-515, arch linux 32 bits.

Are you talking about this?

http://www.vim.org/scripts/script.php?script_id=2009

Or maybe this?

http://www.vim.org/scripts/script.php?script_id=1849

Or something else?

I tried downloading each script and sourcing it in a a new gvim launched with gvim -N -u NONE -i NONE. I could not reproduce the error. I have 7.3.514 on Windows XP 64-bit.
