IPE 7.3.1 crashes when opening a "New Window", citing QWidget::repaint

[abaccarini]

Basically the title, currently on Ubuntu 24.04.1. Running IPE from the terminal and then using the "New Window" menu option yields the following:

➜  ~ ipe
QWidget::repaint: Recursive repaint detected
/usr/local/share/ipe/7.3.1/lua/actions.lua:1484: attempt to index a nil value (field 'doc')
[1]    31752 segmentation fault (core dumped)  ipe

Here's the backtrace:

(gdb) bt
#0  0x00007ffff697a1af in QObject::~QObject() () at /lib/x86_64-linux-gnu/libQt6Core.so.6

Let me know if I can provide any additional info. Thanks for all the work you do on IPE!
