Bug 374001

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): 0x0000555555a6b210 ***
