I have opensuse 13.2 32 bit OS.I have just updated my packages using zypper update command and it did a kernel update.After the updates I am unable to start Google Chrome.
No error message pops up its just that when double click the chrome icon nothing happens.I have uninstalled and reinstalled the chrome several times but no success.
I am running google-chrome-stable-48.0.2564.109-1.i386
Error messages do not normaly “pop-up”. Have you started chrome from the terminal to see what messages it shows?
I am not totally sure how to start chrome from terminal but I ran the command below (as normal user not root) and its output is as shown
~> /usr/bin/google-chrome
Check failed: NamespaceUtils::WriteToIdMapFile("/proc/self/gid_map", gid_)
Well, that is already much more then nothing 
And of course you must run that as the same user that gets the problem in the GUI.
After further research I found you can start it in the manner below
~> /usr/bin/google-chrome-stable %U --disable-namespace-sandbox
[6364:6394:0212/194932:ERROR:nss_util.cc(837)] After loading Root Certs, loaded==false: NSS error code: -8018
but I had hoped for a permanent fix which wont force me to start it from terminal.
Your post follows many others that have posted about the same thing, it’s an upstream problem (likely Google themselves).
If you need Chrome now before a fix is implemented, it does sound like you have the Google repo installed.
Go into YAST > Software Management. Do a search for Chrome. You’ll find a rollback button which might be able to restore an earlier version of Chrome.
Or, you can disable the piece of code that is causing the error described in this thread

In fact other browsers were also affected by this problem. In my case i had problems starting Opera and Chromium. I’m using multiple browsers. The solution was provided with a kernel upgrade and I used a private build and it corrected the solution. I used this repository :
http://download.opensuse.org/update/13.2-test/
and it solved my problem which was identical with the error you posted. In fact it was mentioned both browsers to be affected by this problem.
