rednotebook segfault in Wayland (Ubuntu 22.04)

[pabpou]

I am running a fresh install of Ubuntu 22.04 in a Dell XPS 15 9560 (hybrid NVIDIA/Intel graphics, defaulting to Intel). rednotebook works without issues in X11, but in Wayland it segfaults with the following output:

Thanks for the report! Do you know how to obtain a stacktrace from the core dump?

[pabpou (pabpou)]

I'm not sure how to do that, but I'll be happy to try if you can provide some directions :) There's a .crash file related with the application in /var/crash since the last segfault, I'm attaching it here in case it's useful.

[Jendrik Seipp (jendrikseipp)]

Thanks! This is likely a bug in GTK or Wayland. Google finds many of these for the query "gtk crash wayland", e.g., https://github.com/transmission/transmission/issues/2572. So you could report the problem at their trackers, if you like.

[pabpou (pabpou)]

Thanks. Do you think this could also be related with https://bugs.launchpad.net/ubuntu/+source/celluloid/+bug/1970620? (that one is not a segfault, but a similar Wayland crash of an app that works correctly in X11)

[Jendrik Seipp (jendrikseipp)]

Hard to say...

As of this morning on 22.04, I am unable to reproduce the issue. Do you still suffer from the issue?

[rwe061 (rwe061)]

I have this same type issue on ubuntu 23.04 with wayland desktop, but the XORG desktop works fine.

Any idea how to track down the problem ?

Hi,

By use of the command 'rednotebook' at the command prompt, everyone is using the upstream PPA to run the latest version and are not using the distro supplied version. Is there any particular reason for this?

Support of packages in this PPA are the responsibility of the creator i.e. upstream and all bug reports should be made to the upstream project linked to below.

https://github.com/jendrikseipp/rednotebook/issues

However...

I have tested the 2.31 upstream tarballs and from the PPA and cannot reproduce the issue on:

* Kubuntu 23.04 running wayland.
* Ubuntu 23.04 running wayland.

The easiest next step is to run in python dev mode and see if anything jumps out.

For those using upstream tarball, run:

    python3 -X dev rednotebook/journal.py

For those running the PPA package:

    python3 -X dev /usr/share/rednotebook/run.py

If the complete out can be posted here, it may help in the first instance.

Regards

Phil
