how to debug a Tellico crash (core dump) ? on Ubuntu 25.10, GNOME Wayland

[Daniel Calcoen]

Thanks Robby


I tried ... close, but no cigar ...

alejandra at iMac:~$ tellico
[20:32:07] WARNING QTWEBENGINE_FORCE_USE_GBM environment variable is set 
and it is for debugging purposes only.
[20:32:07] WARNING GBM support is force disabled.
[20:32:07] WARNING GBM is not supported with the current configuration. 
Fallback to Vulkan rendering in Chromium.
