Hi!

While rebuilding the python related packages against the Python 3.15rc2
version we found that python-pyqtgraph fails to build from source:
https://debusine.debian.net/debian/r-python-python3.15/artifact/4933030/

 From the log, the error seems to be:

=================================== FAILURES
===================================
test.)

tests/test_reload.py:73: Exception

Please note that while we ran into this error during the rebuild against
Python 3.15, that doesn't mean that the root cause for the failure is
necessarily the new Python version.

Setting the severity to important for now. Once Python 3.15 is released
and later added to python3-defaults, this bug will become release
critical.

We believe that the bug you reported is fixed in the latest version of
python-pyqtgraph, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1149599@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
