Can not open URLs from chat window anymore

[sithdaddy]

Description

I am using the flatpack version of mumble on Linux Mint.

The issue i am facing is that URLs to websites in the chat window do not open a browser anymore. The emphasis lies on "anymore". It used to work fine until a few weeks ago i think.

• My main browser is firefox. It is set in the system as main browser.
• I have also tried to use Chrome as default browser , it did not help.

When i hover over the URL , the cursor turns to a pointing hand. But when i click on the URL , nothing happens.

Steps to reproduce

1. start flatpack version 1.4.287 of mumble
2. connect to server
3. receive or enter a URL to a website in chat
4. click on that URL in the chat window in order to open the website.

Mumble version

1.4.287

Mumble component

Client

OS

Reproducible?

Does it work with the non-flatpak version? I could imagine this being a sandboxing issue

[sithdaddy]

any idea how it could be fixed ? it looks like the flatpack version is using wine to run mumble ?

Not keen on using non flatpack version its somewhat behind in some features.

[Krzmbrzl]

Conceptually, the packagers will have to somehow punch a hole in the sandbox that allows Mumble to open the browser (if that's what is actually the issue here). But how that works specifically, I don't know.

If you know how that works, self-compiling might be an option (see the corresponding docs).

It seems like something on this specific PC got botched somehow and that is why flatpak mumble does not open URLs anymore.

BTW , same issue with other flatpak programs. none if them can open URLs anymore on this specific PC.

I installed the same flatpak version of mumble on the same linux distro (linux mint) and it is able to open URLs from the chat window.

Is there anything i could look for that might have caused this issue ?

Hm. I'm far from being a Flatpak expert, but something that's always worth a try is to start the program from a terminal window to see whether clicking on an URL prints some sort of error to the console.

Other than that, I would also check whether xdg-open works as expected for URLs.

[sithdaddy]

There is indeed an issues. Here is an extract from the terminal when i click on an URL in the chat window...

...
C42: -> org.freedesktop.portal.Desktop call org.freedesktop.portal.OpenURI.OpenURI at /org/freedesktop/portal/desktop

B473: <- :1.72 return error org.freedesktop.DBus.Error.UnknownMethod from C42
...

xdg-open works fine. it opens URLs without any issues.

[Krzmbrzl]

Looks like some sort of DBus issues. But I don't know what might be wrong :thinking:
