[issue2627] Clone fails with unknown exception: 'empty or missing revlog for .DS_Store

[ewmailing]

New submission from ewmailing <ewmailing at gmail.com>:

When I clone a new repo, I sometimes get the following error:

requesting all changes

The repo I'm dealing with has .DS_Store checked in, but later used hg rm to
remove the files from tracking. They are also now added to the .hgignore list.

However, for situations I don't understand, sometimes new clones work while
other times they don't. 

I sometimes get this error when I try creating/pushing a new repo onto our
server from a Mac to what I believe is a Linux machine. I think sometimes
this fails if I don't have a perfectly clean repo on my Mac. If I do a new
clean checkout and push that one, it seems to help.


This error message pasted above was the result of me trying to clone from a
Mac server via ssh onto a Windows machine. However, using a perfectly clean
repo didn't seem to help in this case.


I've seen this general problem occur with all extensions turned off. Running
hg verify, I see stuff like this:

 data/.DS_Store.i at 0: missing revlog!
 0: empty or missing .DS_Store
 .DS_Store at 0: 8cf95cc043f1 in manifests not found
 data/References/.DS_Store.i at 0: missing revlog!
 0: empty or missing References/.DS_Store
 References/.DS_Store at 0: e959df7694ce in manifests not found
<snip>
 data/tools/drupal/user_service/.DS_Store.i at 0: missing revlog!
 0: empty or missing tools/drupal/user_service/.DS_Store
 tools/drupal/user_service/.DS_Store at 0: e959df7694ce in manifests not found
15892 files, 2494 changesets, 23685 total revisions
294 integrity errors encountered!
(first damaged changeset appears to be 0)

I would really appreciate any help in this matter.
