@ ilija

Thanks for syslog,

I checked log, there is apparmor denail for /dev/nvidiactl
Feb 20 16:28:07 Silver kernel: [  117.797833] audit: type=1400 
audit(1487604487.352:57): apparmor="DENIED" operation="open" 
profile="webbrowser-app" name="/dev/nvidiactl" pid=3124 comm="webbrowser-app" 
requested_mask="wr" denied_mask="wr" fsuid=1000 ouid=0

since  I could not reproduce issue in my pc, I tried in reverse way,
denying apparmor acess to /dev/nvidiactl and I could see exact same
crash.

So To validate that I need your help.
Add path in profile:
$ sudo vim /etc/apparmor.d/user.bin.webbrowser-app
      add /dev/nvidiactl -->     [/dev/nvidiactl rw,]

Reload the profile
$sudo apparmor_parser -r /etc/apparmor.d/usr.bin.webbrowser-app 
$webbrowser-app  // should works.

I am still wondering why crash is not happening in any other
machine(including mine)
