[Qgis-user] Qgis startup crashes on Debian 10

Again as we saw with builds earlier this year, the latest 3.10.11 build 
will crash on startup. This happens on anything I can find running 
Debian 10.

There aren't seen anything similar on Ubuntu.

Is there likely to be some sort of issue with the build environment that 
affects Debian 10 compatibility?

The below is a K crash dump.

Application: qgis (qgis), signal: Segmentation fault
