Hi Michael,

Thank you for the quick reply. I see that you have already committed a fix. 
I created a ticket nevertheless, Bug #1868680 on LP.

This is not hugely urgent, the security implementation works nicely, just that the reload does not work as it used to and as the documentation still claims.
    
    It's a bug.  It looks like I completely mis-read this code in asCa.c
    and thought that asCaStop() was actually causing the worker to break.
    It isn't.
    
    I think the fix is to revert afc31f2f064974e97ef61a9dc6cc58692a1b0a5f
    and then cleanup the indentation...
    
    Would you like to create a ticket for this?
