[Bug 1548425] Re: update-manager crashed with AttributeError in check_hovering(): 'tuple' object has no attribute 'get_tags'

[Brian Murray]

** Description changed:

+ Impact
+ ------
+ We are receiving thousands of crash reports regarding update-manager when it is used in conjunction with the gnome3-team ppa which provides a new version of gtk3.  Here is the Errors Bucket:
+ 
+ https://errors.ubuntu.com/bucket/?id=/usr/bin/update-
+ manager%3AAttributeError%3Avisibility_notify_event%3Acheck_hovering
+ 
+ 
+ Test Case
+ ---------
+ On an Ubuntu 16.04 system
+ 1) sudo add-apt-repository ppa:gnome3-team/gnome3-staging
+ 2) sudo apt-get update
+ 3) sudo apt-get upgrade
+ 4) reboot
+ 5) downgrade whoopsie (sudo apt-get install whoopsie=0.2.52 libwhoopsie0=0.2.52)
+ 6) open a terminal
+ 7) run update-manager
+ 8) observe Traceback re: "AttributeError: '_ResultTuple' object has no attribute 'get_tags'
+ 
+ With the version of the package from -proposed you will no longer
+ receive a traceback.
+ 
+ We can also verify that the bucket at the Ubuntu Error Tracker does not
+ contain the new version of update-manager in the versions table.
+ 
+ Regression Potential
+ --------------------
+ Little given that the patch uses a try / except handler for the AttributeError.  That being said we should try installing the version of update-manager from -proposed on a system without the new version of gtk3 and upgrading packages.
+ 
+ 
  Unexpectedly crash on close.
