Steps to reproduce

1. Login to owncloud and navigate to 'users'
2. Type any invalid name (ending with a whitespace ) in the placeholder 'Group...'
3. Click on '+' button (Button to add a new group)

Expected behaviour

The message saying Error creating group: Invalid group name should be popped up.

Actual behaviour

The actual pop up says Error creating group: {message}

The issue is not in the API because on making API call to add a group "newgroup ", it returns the correct error message.

API Call

curl -X POST http://admin:secret@example.com/ocs/v1.php/cloud/groups -d groupid="newgroup "

Obtained Response

<?xml version="1.0"?>
<ocs>
 <meta>
  <status>failure</status>
  <statuscode>101</statuscode>
  <message>Invalid group name</message>
 </meta>
