Just want to add a permanent solution to the problem:
1. Open google-chrome located in /usr/bin with ‘gedit‘, ‘kate‘ or your favorite text editor.
gedit /usr/bin chromium-browser
2. Add "--user-data-dir" (without the quotes) at the very end of the file. Mine looks like this:
exec -a "$0" "$HERE/chrome" "$@" --user-data-dir
3. Save, close and voilà, you‘re done. Enjoy your favorite browser.
