Traits test suite failing with PySide 6.7.0 #1787

Closed mdickinson closed 2 months ago

mdickinson commented 2 months ago

The Traits test suite appears to be crashing with a segfault with the recently released PySide 6.7.0.

Here's a traceback:

Minimal reproducer:

from traits.api import HasTraits, Int
from traitsui.testing.api import UITester

class HasInt(HasTraits):
    foo = Int()

obj = HasInt()
with UITester().create_ui(obj):
    pass

Output of the above when run:

If I remove the UI tester involvement I get a different failure (a TypeError). The following script:

from traits.api import HasTraits, Int

class HasInt(HasTraits):
    foo = Int()

obj = HasInt()
obj.configure_traits()

gives:
