filtering and "Unknown element type specified: !"

Description

Fatal Error is thrown within a scenario where the search area is used

Distribution Name and Version

Debian Strech

FusionDirectory Version

1.2.1-1

PHP version used

Stock, untouched PHP7 config

Origin of php packages

FD's own repositories

Steps to Reproduce

Unfortunately, I can only reproduce the following with my specific LDAP content. It doesn't occur on demo.fusiondirectory.org

  1. Navigate to 'users'
  2. Use the text area on the right and type a (known) username and click 'apply filter'.
  3. Now change to 'systems' section.
  4. Navigate back to 'users'

Expected behavior:

on step 4, I should get the filtered list of users

Actual behavior:

Fatal error: Uncaught Exception: Unknown element type specified: ! in /usr/share/fusiondirectory/include/class_filter.inc:389 Stack trace: #0 /usr/share/fusiondirectory/include/class_listing.inc(484): filter->render() #1 /usr/share/fusiondirectory/include/simpleplugin/class_simpleManagement.inc(523): listing->render() #2 /usr/share/fusiondirectory/plugins/admin/users/class_userManagement.inc(119): simpleManagement->renderList() #3 /usr/share/fusiondirectory/include/simpleplugin/class_simpleManagement.inc(595): userManagement->renderList() #4 /usr/share/fusiondirectory/include/simpleplugin/class_simpleManagement.inc(1337): simpleManagement->execute() #5 /usr/share/fusiondirectory/plugins/admin/users/main.inc(22): simpleManagement::mainInc('userManagement') #6 /usr/share/fusiondirectory/html/main.php(280): require('/usr/share/fusi...') #7 {main} thrown in /usr/share/fusiondirectory/include/class_filter.inc on line 389

At this point, if I point the browser to root's FD at /fusiondirectory, I got the red message:

 Error 	Fatal error
FATAL: Error when connecting the LDAP. Server said 'Could not bind to (while operating on LDAP server )'.

Please fix the above error and reload the page.

If I reload that page, I got the login screen back again where I can login again BUT when I navigate to 'users' section I got the same Fatal Error as before again.

The only way to workaround the problem is to clear the cookie attached to fusiondirectory, and login again.

Reproduces how often: 100% but on the said system

Additional Information

I can provide access to a test instance loaded with this data.
