+### Please describe the problem.
+On one repos, I cannot run vicfg because git annex complain that
+
+    git-annex: /home/moi/Bibliothèque calibre/.git/annex/config.tmp: commitBuffer: invalid argument (invalid character) failed
+    git-annex: vicfg: 1 failed
+
+Note that the assistant and the webapp seem to be working as it should, giving me the possibility to make most of the configuration I want.
+
+The problem does exit on all the clone of the repos.
+
+
+### What steps will reproduce the problem?
+
+I don't know if the "è" in the directory name is linked to this. It seem also that the description of one of the repository has been incorrect (something like "toubib: ~/Biblioth⯁⯁⯁que calibre/" where the three ⯁ replace one incorrectly encoded char that was, since then, changed.
+
+
+### What version of git-annex are you using? On what operating system?
+I'm using the more uptodate version that are in Debian sid:
+
+$ git --version
+git version 2.1.4
+$ git annex version
+git-annex version: 5.20141125
