Not compatible with PyQt 5.7 / Qt 5.6

[groovy]

I don't know what exactly leads to this error as the installed version worked before. It is maybe related to some recent system updates. This is what I get:

QObject::connect: Cannot connect OffloadManager::downloadFolders(PyQt_PyObject) to (null)::folders_generated(PyQt_PyObject)
ERROR An unhandled exception occurred

My initial reaction is that you're running into problems with PyQt 5.7, which is very bleeding edge. I have not tested it at all myself. Can you easily drop back down to PyQt 5.6 on Gentoo?

Plus I'd recommend Python ZeroMQ 15.1.0, as I've seen problems with the main process not exiting when using Python ZeroMQ 15.2.0. It might be different on your system however.

Thanks for the quick reply.
I will have a look at downgrading these packages and report back here.

[groovy (paessler)]

You are right. Downgrading PyQt to 5.6 makes it work again.

[Damon Lynch (dlynch3)]

I've fixed the bug, which relates to more strict enforcement of the Qt signal/slot mechanism by PyQt starting with PyQt 5.7. It was a two line fix, thankfully.

I am on debian and cannot downgrade. When will this fix be out?

[Damon Lynch (dlynch3)]

Whenever alpha 5 is ready to release. Hopefully this month.
