Hence assigned/cced to the file owner from the below link to assign it to an appropriate dev person.
Currently its impacting to the latest Stable (51.0.2704.84) & Beta (52.0.2743.33).

From the stack trace, it looks like this is crashing because profile_ is null when the following line is reached: https://cs.chromium.org/chromium/src/chrome/browser/ui/app_list/app_list_view_delegate.cc?sq=package:chromium&type=cs&l=827

Assigning to one of the owners of that file from chrome/browser/ui/app_list/OWNERS

Fix crash in app list view delegate.

This CL fixes an issue where an observer was not removed from the
app list view delegate when the profile was set to nullptr. This caused
a crash if the TemplateURLService notified the app list view delegate.
