[PyQt] Deadlock when endResetModel() triggers QQuickImageProvider asynchronously

[Milorad Pop-Tosic]

Hi,


We're experiencing a deadlock when resetting a list model assigned to a QML ListView which in the delegate has an Image that calls QQuickImageProvider with asynchronous: true. The execution never reaches requestImage in  QImageProvider. If asynchronous is false, everything works fine.


I also tried subclassing QQuickAsyncImageProvider, but that behaves the same.


The same example in C++ seems to work.


The gist is here: https://gist.github.com/poptosic/b341511d3a0a6b7f09278ce5da7e20e7


Tested on PyQt5.8.1 on Windows.


Are we doing something wrong here?


Thanks,

Milorad
