Seeing what appears to be the same crash on my system:

Problem showed up after updates yesterday (05-JUL-2017)

I get the same error since today. Works if do not sign in to my profile or disable extensions. But only using single screen on laptop.

Lenovo Yoga 900, 
Chromium 59.0.3071.109 Built on Ubuntu , running on LinuxMint 18.2
Linux risa-mint 4.10.0-26-generic #30~16.04.1-Ubuntu SMP Tue Jun 27 09:40:14 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Also tried with Kernel 4.8.0-58 but no difference.

Seeing the same error on my system. 

rm -r ~/.config/chromium let me (temporarily) sidestep the issue, but I suspect that a recent chromium update is causing this bug.

I'm also running linux (ubuntu 16.04 LTS) on a Lenovo machine (X1 Carbon 2nd ed.) 

Also receiving this error on my system.

I am too running on a Lenovo machine (IdeaPad U330T) on Ubuntu 16.04 LTS. Disabling extensions seems to fix the problem, but the problem did not appear until the last update.

More info based off of others people's experience.. I'm also running on a Lenovo (T470s). I experienced the same issue with extensions installed and with a freshly installed browser with no extensions installed. 

This has been happening to me as of a few days ago. Running Linux Mint 18.1 Cinnamon v. 3.2.7 64 bit on a Thinkpad T420.

Am able to get around it by using chromium-browser --disable-extensions.

Crashes happened on existing install of Chromium as well as fresh install.

Tested on Chromium  #59.0.3071.0 on Ubuntu 16.04(Desktop machine) and unable to reproduce the issue. Adding the label ‘TE-NeedsTriageFromMTV’ as 16.04 Ubuntu laptop is not available with us. Could someone from MTV please look into this issue.

I see you're running the chromium-browser that ships with Ubuntu.  Could you either
1. File a bug with Canonical.  (It's impossible for Google to get crash reports with Chromium)
2. Try with google-chrome-stable and if it still crashes, post the crash ID

I tried 2 and can't reproduce the issue with google-chrome-stable. But about reproducing, it seems that the issue occurs occurs on Lenovo laptops and Chromium 59.0.3071.109.  

Thank you for providing more feedback. Adding requester "pbommana@chromium.org" to the cc list and removing "Needs-Feedback" label.
