Hi, 

When I am working in an indirect buffer and am currently clocked into a subheading. If I refile this subheading and then run org-clock-out, I get the error "Clock start time is gone".

When not working in an indirect buffer, Org Mode is able to track this subtree and clock out of it, which is the expected behaviour. 

Thanks in advance. 

Regards,
