ReTexT crashes when switching from preview back to edit

[raffaem]

When I switch from edit to preview all is fine.

When I switch from preview back to edit, ReText crashes.

Here is the console output:

Removing the configuration file with:

rm "/home/raffaele/.config/ReText project/ReText.conf"

have fixed it, but I had lost my work due to the crash!!!!!!!

[raffaem]

The crash happens when I enable the WebKit renderer

[mitya57]

I am sorry for this crash. It's a duplicate of #573, which I received and fixed last week. I will make a new 7.2.3 release ASAP.

[raffaem]

Yeah it's fixed in retext-7.2 branch. I had problems in switching to Python 3.10 too. Thanks!

[raffaem]

Just curious: what's the master branch for?

[mitya57]

It's for the next major release, 7.3 or 8.0. This issue does not affect master because Qt WebKit support was removed there. See 84600d0b1923fe9b for an explanation.

[raffaem]

Thanks :)

What is the alternative? WebEngine? How do I make ReText use WebEngine?

[mitya57]

Yes, the alternative is WebEngine.

First, make sure it's installed (apt install python3-pyqt5.qtwebengine or pip install PyQtWebEngine).

Second, replace useWebKit=true with useWebEngine=true in the configuration file.

[mitya57]

The new release is done now.
