Bug Description

[ 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.

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.

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.

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.

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.

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.
