Thanks for your discovery.

I interpreted the implementation of the function
“thunar_thumbnailer_queue_async_reply” in the way that there is a specific lock
type applied.
I imagined that a deadlock can only happen then if this function is executed
once more before an unlock would be performed.
* Does the aspect “reentrancy” matter here?
* Is there a need to use recursive locks?

Is a job queue management relevant for the affected use case?
