VLC exits after flashing a title with Privacy and Network Access Policy in Ubuntu 16.04 32-bit

[trappedinspacetime]

First of all thank you for developing flatpak environment and adding vlc to repo.
I installed vlc with flatpak install --user flathub org.videolan.VLC command.
When I tried to run it like flatpak run org.videolan.VLC, it exits immediately after a gui flashes a title with "Privacy and Network Access Policy" then it disappears. I searched for it on the net, some say that it's a bug related to vlc when you launch it first time, and suggested a workaround by launching it like

 flatpak run org.videolan.VLC --no-qt-privacy-ask

That way suppresses the dialog, however vlc still keeps exiting.
I hope you help me.
Regards.
Kenn.

I can't reproduce this; the very first time the app starts up, I can see that window but it does not flash and when I close it, the app is running fine.

Are there any other messages on the terminal after the application exits?

@cosimoc thank you for responding. I am on Ubuntu 16.04 32 bit platform.
Here is the output of terminal:

@kensully I wonder if this is an issue for 32-bit platforms, or perhaps the real issue is that locales don't seem to be installed? Can you try to install org.videolan.VLC.Locale explicitly and see if that changes anything?

[trappedinspacetime]

@cosimoc I tried to install it like flatpak install --user flathub org.videolan.VLC.Locale it says it's already installed.

[trappedinspacetime]

I cloned this repo and built it via flatpak-builder --repo=VLC org.videolan.VLC org.videolan.VLC.json but the result is the same, it crashes.

[trappedinspacetime]

I switched architecture to x86_64 and VLC runs well. It appears to be 32 bit support issue.

[trappedinspacetime]

I wonder why it complains about Gtk-Message: Failed to load module "canberra-gtk-module", how can I install canberra-gtk-module package into flatpak environment?

Some configuration on the host is probably leaking through with the canberra module. As a user there is nothing to do and I don't think we should bundle the module here because it doesn't provide anything useful so its just a harmless warning.

[trappedinspacetime]

@TingPing Thank you for responding, do you know any way to manually install a package into flatpak environment?

[TingPing]

If I wasn't clear; There is no reason to have that module its not useful.

[trappedinspacetime]

This might be related core dumped error

I tried the following :

   $ flatpak run --command=sh org.videolan.VLC 

    sh-4.3$ vlc -I skins2

it launches the VLC GUI with the skin2 but crashes again with core dumped error when I click VLC menu on the skin.

You can try flatpak run org.videolan.VLC -vvv to see if we get more infos.

[trappedinspacetime]

@MatMaul thank you for responding. I added debug output to this gist

[MatMaul]

Ok nothing helpful.
Let's try to get the backtrace:

flatpak run --devel --command=sh org.videolan.VLC
gdb vlc
r

Then it should segfaults, do a bt and paste the output.

[MatMaul]

oh and install org.videolan.VLC.Debug before doing all of that or the backtrace will be a lot less useful ;)
edit: org.freedesktop.Sdk could be useful too

[trappedinspacetime]

@MatMaul here it is vlc debug gist

[MatMaul]

I think you didn't do the bt at the end.

[trappedinspacetime]

@MatMaul thank you for your help. I am not familiar with gdb so missed bt step.
gdb bt

[MatMaul]

Did you do the bt right after the crash ? You should see the last line of the first log (xcb_send_request_with_fds64) in the backtrace.

[trappedinspacetime]

Yes, I did. I reran the steps above but only posted bt part since I posted it in the previous post.

[MatMaul]

Probably not, looks unrelated. no idea for now this backtrace makes no sense, those python errors are weird and seem to have been generated by gdb itself when printing the trace. You did install the Sdk and Debug packages as I mentioned right ?

[trappedinspacetime]

Yes, I installed them.

[trappedinspacetime]

You are right about it by saying

those python errors are weird and seem to have been generated by gdb itself when printing the trace
gdb bug

[MatMaul]

Please reopen if still not working.
