            Bug ID: 374001
           Summary: kaccounts-integration crashes when configuring some
                    online accounts
           Product: KAccounts
           Version: git-latest
          Platform: Compiled Sources
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: KCM
          Assignee: kde-telepathy-bugs at kde.org
          Reporter: Kwanza.Pili at virginmedia.com
  Target Milestone: ---

The latest version kaccounts-integration (16.12.0) cannot create some types of
online accounts (e.g. google, facebook, ...). The generic error is "cannot find
generic-oauth plugin" despite the fact that the plugin is installed. To access
it, I ran "kcmshell5 kcm_kaccounts" under gdb. After the app starts, I choose
"Create" which brings up the menu list. Then choose any of the offending
protocols (e.g. google or facebook). An error dialog appears complaining about
the oauth plugin. Then the segmentation fault results with the following
backtrace:

*** Error in `/opt/kde/bin/kcmshell5': double free or corruption (!prev):
