apt-cache policy unity
unity:
  Installed: 7.4.5+16.04.20180221-0ubuntu1
  Candidate: 7.4.5+16.04.20180221-0ubuntu1

Tried scenario multiple times, it doesn't happen here as it was not
happening most of the times before, being this crash pretty random.
However the change seems sane, so I think we can verify.

Feel free to reopen in case.

Hello Josy, or anyone else affected,

Accepted unity into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/unity/7.4.5+16.04.20180221-0ubuntu1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

** Description changed:

+ [ Impact ]
+ 
+ Unity ramdomly crashes when hovering a tooltip or opening a quicklist
+ 
+ [ Test case ]
+ 
+ 1. Hover a launcher icon
+ 2. Open a quicklist or wait for the tooltips
+ 3. Unity should never crash during such operation
+ 
+ [ Possible regression ]
+ 
+ The view might be opened without blurring background, but still better
+ than crashing.

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix.
These types of crasher are better handled by errors.ubutnu.com which can 
collate similar crash reports to help us identify persitent bugs rather than 
one-off crashes.
Sorry we are not able to help with this specific issue. If you are still 
experiencing this crash, please re-open the bug and add the tag 
"desktop-bugscrub-reopened". See https://wiki.ubuntu.com/BigDesktopBugScrub for 
more information.

This bug occurs for me only when I have applied a different theme(Numix)
than the defaults  using the unity tweak tool and while scrolling down
the unity launcher to reveal hidden application icons.
