Thank you for providing more feedback. Adding the requester to the cc list.

Full stack trace attached.
OK here's how I reproduced it.
Following the instructions in
https://wiki.debian.org/Chromium/Debugging
I installed
chromium-dbgsym:
  Installed: 65.0.3325.74-1+b1
and as user 'nobody' on a fresh account,
first installed extension adblockplus, which promptly crashed.
Now restarting the browser this time via
chromium --debug 2>&1 | tee xgdb-chromium.txt
I produced a trace wherein you can see in excruciating detail what
happened.

Now I cleaned out all of user nobody's files and started again with no
extensions, which didn't crash. Attached is Normal*.txt for that case.

Issue is not reproducible from ET team and Inhouse team based on comments#2 and comment#5. As issue is not reproducible from TE end removing requesting someone from Platform>Extensions team to have a look at this issue. Hence adding TE-NeedsTriageHelp label.

Thanks!

Thanks for opening the bug downstream.  This only appears to be a problem on Debian, so I'm closing this issue.
