Hi Python community.
I encounter a freeze testing PySide.
Reproduce bug.
Copy past the content of the jointed file in a Python script editor and
execute it.
This create a new pane using:
Pane/Test Table Panel
Now nuke freeze (CPU 100%) with this backtrace:

After some search, this is related to the line 25 of my given script:
filterLay.addLayout(filterLay)
I suppose there is a problem as Python go into an infinite loop and
should just raise Exception no? Am I wrong?
Regards,
Dorian
