Strange permission problem - advice needed

[Ian Hobson <ian@ianhobson.co.uk>]

Hi all,

I'm using git on windows (XP) and the GUI told me there were too may 
objects so I allowed it to tidy up. It errors, that it could not unlink 
some files. So I checked the properties - all files are readable.

I repeated the gc in git bash with the following results.

$ git gc
Counting objects: 398, done.
Compressing objects: 100% (205/205), done.
Writing objects: 100% (398/398), done.
Total 398 (delta 191), reused 398 (delta 191)

$ git version
git version 1.7.0.2.msysgit.0

Note - this is Windows XP so there are no permissions on the files. The 
files are all local.

I even disabled AVG and tried again. Same result.

What is going on? and does it matter?

A thought - I copy/pasted (not cloned) the whole repo from a Samba share 
(presented by Ubuntu) about 2 weeks ago. Could it be something left
over from that? The share was read/write and I owned all the files.

Thanks

Ian
