Bug#1129753: libvulkan1: segmentation fault while running epiphany-browser

Package: libvulkan1
Version: 1.4.341.0-1
Severity: important
X-Debbugs-Cc: [email protected]

Dear Maintainer,

I run ephiphany-browser routinely once a day, for a hour or so. 
Every couple of days I get a segfault, which crashes the browser 
and sometimes locks up the machine. 

The content of syslog looks like this :
