I have no problem when I use an relative path like srcdir = '.'.
I have an other issue with the po plugin when I set the srcdir to './doc/' (provided that my config file is in /path/to/repo). In this case the po plugin try to add 'doc/doc/index.fr.po' which does not exists (seems like the srcdir path is prepended twice).
