gitk / diffcore-rename error message

["Alf Clement" <alf.clement@gmail.com>]

Hi all,

I was trying to create a git repository in the following way (while
importing different releases from clearcase tree)

git init .
tar xzf version1..
git add .
git commit -a -m"Version1"
rm -rf tree
tar xzf version2
git add .
git commit -a -m"Version2"
... and so on for next next verison.

Now I get the following error while using gitk:
warning: too many files, skipping inexact rename detection
warning: too many files, skipping inexact rename detection
    while executing
"close $bdf"
    (procedure "getblobdiffline" line
...

which seems to come out of diffcore-rename.c

Can I ignore it? Is it harmful?

Thanks,
Alf
