All I did was specify the connection type explicitly. It's possible that means the signal was no longer connected properly, but as I understand the documentation that should not be the case. The watchDir signal I added to FileManagerListJob myself uses this type and works as expected. I haven't checked if removing the explicit connection type makes any difference there.

In essence, no. Either it's not received at all, or not at the right time, or with the wrong context.

Standard but advanced and probably very annoying debugging...

Let me ask the complementary question: why would it be safe here to connect a signal sent from a background thread to a slot in another QObject that will be executed on the main thread?
