You're right. Btw my main goal was just to make vermin to detect the
minimal version of this script.

I tried to run this script on Fedora 41, installing PySide with
pip there (*):

	$ pip install --user PySide2
	...
	$ perf record  ls
	...
	$ perf script -s tools/perf/scripts/python/export-to-sqlite.py pt_example branches calls
	Segmentation fault (core dumped)


but it gives me segmentation fault on a required library:

	Program terminated with signal SIGSEGV, Segmentation fault.
	#0  0x00007fcab2e0d1ec in SbkObject_TypeF () from ~/.local/lib/python3.13/site-packages/shiboken2/libshiboken2.abi3.so.5.13

(*) Fedora 41 doesn't have pyside2 packages anymore. 

Thanks,
Mauro
