PyCall together with ImageView crashes

[roflmaostc]

Hey,

I encountered the following crash:

julia> begin
               using ImageView
               using PyCall
       end

julia> begin
               pygui_start(:qt5)
               qapp_obj = pyimport("qtpy.QtWidgets").QApplication([""])
       
       end

I'm using Julia 1.5.3 on Arch Linux with PyCall v1.92.1 and ImageView v0.10.12.

Any ideas what's going on?

Thanks,

Felix

The two packages I use the most!... I have noticed that for me I may get an error loading ImageView after pyplot, but if I load ImageView before it seems to be fine?
