Traits package in Anaconda default channel is broken

Linux / python 3.13
When I install traits from the default channel via

conda install python=3.13 traits

and then try to use it

python

import traits.api as tr

I get the following error:

Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    import traits.api as tra
  File "~/miniconda3/envs/traitstest/lib/python3.13/site-packages/traits/api.py", line 17, in <module>
    from .constants import (
    ...<7 lines>...
    )
  File "~/miniconda3/envs/traitstest/lib/python3.13/site-packages/traits/constants.py", line 13, in <module>
    import traits.ctraits
ImportError: ~/miniconda3/envs/traitstest/lib/python3.13/site-packages/traits/ctraits.cpython-313-x86_64-linux-gnu.so: undefined symbol: Py_TRASHCAN_SAFE_BEGIN

I guess this means that the binary in the traits package does somehow not fit the python that is delivered via the same default channel.
This does not happen if I install via conda-forge channel.
Can someone reproduce this? I would be good to have a solution here.
