Comment 1 Ivan Zakharyaschev 2023-06-02 05:20:53 MSK 
No, it's not related to python3 being statically linked to libpython3 now:

the crash is also present in p9, where python3 was dynamically linked to libpython3.

Это надо чинить одновременно с обновлением slicer
Comment 3 morozovaes@altlinux.org 2023-06-23 15:51:26 MSK 
You're right, it's absolutely unrelated to changes in ALT-linking; this issue originates in CTK upstream: any attempt to import PythonQt modules outside of a Qt application produces a segfault:

https://github.com/commontk/CTK/pull/520

The current solution as of commit https://github.com/commontk/CTK/commit/a203172b634253cc3717346de30305ffe721d91c and further
is to skip such imports by standalone python interpreter. It will be included it the next CTK package release.
