Yes, I have an OBS repo enable from the user Dead_Mozay
(https://download.opensuse.org/repositories/home:/Dead_Mozay/openSUSE_Leap_15.1/x86_64/)
to install the pycharm-community IDE. However I put this repo with a lower
priority relative to the main repos.

Meanwhile I installed a fresh Leap 15.1 installation on a virtual machine,
updated it and installed every component you listed in your test in the same
order. The IPython in spyder actually behaved fine! I enabled the Dead_Mozay
repo, installed pycharm-community (with its dependencies), and no problem! I am
quite puzzled but I think of two hypothesis:
1) Something went wrong during the upgrade from Leap 15.0 to Leap 15.1.
2) I messed up something while enabling certain repos to get software I wanted.

The latter is probably the most likely and although I try to be careful,
sometimes stuff happens. At this point I find it hard to pin point when the
problem started to happen.
