StGIT munged path on refresh

[Andy Green <andy@warmcat.com>]

Hi folks -

I have been using quilt with some success and now I am trying to migrate
to stgit.  I can get started okay with stg init and stg new "mypatch",
stg refresh then picks up modifications without having to be told about
the changed files, very nice.

However after I have modified several files in the tree, stg refresh
breaks without my having changed anything in the meantime to do with
stgit.  The problem looks like this:

$ stg refresh
Checking for changes in the working directory... done
Refreshing patch "mISDN-remove-unused-test-from-bitops.patch"...error:
drivers/isdn/hardware/mISDN/drivers/isdn/hardware/mISDN/appl.c: does not
exist and --remove not passed
fatal: Unable to process file
drivers/isdn/hardware/mISDN/drivers/isdn/hardware/mISDN/appl.c
stg refresh: Failed git-update-index

$ pwd
/projects/octotux/packages/mISDN-1.2.0/drivers/isdn/hardware/mISDN
$ ls appl.c
appl.c

The tree starts at /projects/octotux/packages/mISDN-1.2.0, ie, there is
a .git/ in there.  Notice that in the diagnostic, the path after the
start of the tree is repeated twice :-( but I did not run any stg or git
commands between a successful stg refresh and the first broken one.

In case it is important, I am working on a branch called "portability".

This is with

# rpm -q git-core
git-core-1.5.0.6-1.fc7
# rpm -q stgit
stgit-0.12.1-2.fc7
