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
