Git svn rebase: file out of date - trailing whitespace

I have an issue while using git svn. I have a repor which is used by people mostly from Windows but I use Linux.

I have performed changes on this repo but today I got this after git svn dcommit:

Could not chdir to home directory /isource/home/pmalek: No such file or directory
        M       robot_tests/XXXXX-XXXXX_tests/testcases/03.01.test.tsv

        M       robot_tests/common_keywords/XXXXXKeywords.tsv

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".

rebase refs/remotes/git-svn: command returned error: 1

I have a clean commit in my local repo but cannot do the git svn dcommit. File to commit has trailing whitespaces but it's ok.

What should I do ?

I have tried many things in .gitconfig but none worked. Current .gitconfig

[core]
   autocrlf = true
   whitespace = cr-at-eol

Solution

git svn dcommit only works if your git branch is a superset (i.e., more current than) the newest SVN revision). If this is not the case, you have to import the new SVN commits first. This is done via git svn rebase.
