Helper processes don't quit #3421
Description
Describe the bug
Helper processes that (I think) serve the clipboard content don't quit after another clipboard item is copied or selected from Copyq. Thus leaking processes.
To Reproduce
Repeatedly select an item from Copyq.
Expected behavior
The helper process should quit as soon as another item is selected or other data is copied.
Screenshots
I can't seem to upload any screenshots, but this is the process list after spamming a couple of times.

Additional context
Here's the log since the most recent startup, though I don't think there's anything relevant in there. Even the crashes seems to be a different process from the leaked ones.
