Errors (and lock up) on starting Frescobaldi

[Raphael Mankin]

I have recently upgraded from xubuntu 20.04 to 22.04.
Now Frescobaldi will not start. I tried a reboot, but that did not help.

I get a popup window showing:

Traceback (most recent call last):
  File "/usr/share/frescobaldi/frescobaldi_app/widgets/linenumberarea.py", line 83, in paintEvent
    rect.moveTop(geom.top())
TypeError: moveTop(self, int): argument 1 has unexpected type 'float'

If I start it from the command line, I get :

I have tried:

apt purge frescobaldi
apt autoremove
apt install frescobaldi

but with no success.

I have now managed to download and install the .deb for version 3.0.0 and, with a certain amount of fiddling to install missing bits and pieces, this now works.

Status changed to 'Confirmed' because the bug affects multiple users.
