Comment 1 Dirk Wiesenthal univentionstaff 2016-06-13 11:13:59 CEST
I am not sure how critical this is. The test is only run during uninstall. And uninstall normally requires a registered App, so that ldap_object may not be None. This may happen when another session uninstalled the App and then one tries to uninstall it, maybe?

Anyways, fixed in
  univention-appcenter 5.0.21-7.170.201606131112

by testing for ldap_object "existence".
