Crash while marking episodes as played

[KimHono]

Hi !
I read other issues about crashes, but without real fix. So, here is my case : Vocal crashes as soon as I select all episodes and select "Mark this episode as played".
I captured the full output, which is :

With hope this will help...

Thanks !

Hi @KimHono! Thanks for the report. We just released 2.4.0 and are in the process of pushing the updates to Flathub/AppCenter. This code was completely changed between 2.3 and 2.4, so I believe this should be fixed now (I can't reproduce on my side). When the update arrives for your system will you please try it and let me know if you're still having these crashes? Thank you!

Hi @nathandyer ! Thanks for your detailed answer. Unfortunately, I've got the same problem : Vocal crashes when I try to mark several episodes as played. The only possibility is to select one by one.

Here is my terminal output recording this action:

Thanks @KimHono! I'll take another look.

I encounter what seems a similar issue when opening a podcast. I can open a new issue if needed.

I ran into a similar issue today, after a bit of troubleshooting it turned out that this is actually caused by an upstream Gtk Bug. I just pushed a commit with a workaround for that(+ a fix for another crash I encountered while troubleshooting this) to the branch of my already opened PR.
Note that there are still bugs when trying to mark multiple episodes as played, I will probably take a look at that in a couple of days.

[KimHono]

I think the issue was resolved with version 2.4.2-x (I'm now on 2.4.2-2).
