I’ve been able to partially retrace the attached crash in a xenial VM.
The top of the stacktrace looks like this:
#0 0x00007f34785ad06c in pushbuf_kref (push=push@entry=0x5562e3e8adc0, bo=0x0,
flags=<optimized out>) at ../../nouveau/pushbuf.c:167

Title:
Web Browser crashes randomly and sometimes with the entire system
Status in webbrowser-app package in Ubuntu:
Confirmed
Bug description:
On my system the web browser can surf web pages but in a few seconds
it crashes the app and sometimes my hole system, making it
unresponsive and I have to switch off power (maybe kernel panic?).
This happens the same with snap and debian versions. The crash file
generated in /var/crash is attached below.
And here is what it displays in the terminal when crashing (There are
a few sentences in spanish):
