gitg killed my stash

[Guilhem BONNEFILLE <guilhem bonnefille gmail com>]

Hi,

I don't know how to report this issue, so I send it to the list.

I don't know what precisely occured.
With 0.0.4, I deleted a stash from the middle of history, not from the
upper part of the list. gitg crashes. But, while crashing, it
overwrite .git/refs/stash with a single line containing a 00..00 SHA-1.
I really don't knwo what occured, so no idea how to fix this.

Note that in this situation, gitg is unable to run: git is unable to
parse refs, so gitg gets a zero length list of refs in load_refs, and
so... segfault.

A minor improve can be to apply the following patch:

diff --git a/gitg/gitg-repository.c b/gitg/gitg-repository.c
