Cannot enable MS Word Support

ownCloud 9.1.3 (stable)
php 5.5.9

When I check "locale" option to enable MS Word support the admin page refresh and option backs to disable.

Same issue in oc 8.2.x.
Workaround: set field "converter" to "local" and field "converter_url" to "http://localhost:16080" in tables "oc_appconfig" directly in oc mysql database.

The issue is not present in oc 8.1.
