My stash wants to delete all my files

Heya, I've run into a problem with git stash. I suspect that I've already lost the work that I tried to stash, but would like to know where I went wrong.

I had some work in progress, wanted to check something from my last commit, and typed "git stash". I forgot to "git stash apply" immediately afterward, and carried on doing some more work related to the stashed code. I realized that I'd got a stash that I wanted to apply, and tried to restore it. While trying to restore it, I typed "git stash --apply", which actually created a new stash named "--apply". Ooops. Anyway, the real problem is :

$ git stash list stash@{0}: On master: --apply stash@{1}: WIP on master: 09e3c30... Better handling of cell sizes in the grid

$ git stash show stash@{1}

Hmm. Looks like it's trying to delete all of my versioned files. "git stash apply stash@{1}" confirms this. Obviously that's not what I tried to stash - my WIP when I stashed was a few additions, a couple of new unversioned files, and moving a few lines of code from one file to another.

Any ideas what happened there? I can't seem to reproduce the problem in a test repository.

Cheers, Jon
