There seems to be two problems here: the completely malformed UPnP descriptor and/or poor error handling of this type within the gupnp library.

Once connected to the router, can you identify the IP address of it? With that you can try browsing to http://<ip-address>:5351/rootDesc.xml and attach here the XML source.

Regards,
Daniele

rootDesc.xml added

Hi, I finally fixed the snap build of the version 0.3.4. Could you try updating the app and test again?

[MaSo_CZ (mzettik)]

Great, thank you.
I tried the update and it doesn't seem to crash anymore.
It runs for over 2 hours and holds.
It just shows some warning, but apparently it's not related to this.

I expected that the application could display more things on the router and possibly set some issues :-)

Anyway, I uncovered some mysterious communication of one phone with this app. It just could show more details about the end device (which is connected to the router) (only shows IP and ports)

On this app is "Add" and "Remove" port forwarding. Missing "Edit" selected entry.

If there are any mistakes, I'm sorry, I'm using Google Translate :-))

Thank you :-)
