[Bug 1399993] [NEW] Unable to open Software Updater after it automatically checked for updates

[Lizhou Sha]

Public bug reported:

Software Updater checks for new updates daily, and when it has found
updates, it displays an icon on the launcher. Clicking on the launcher
should open Software Updater, whereupon the user is prompted to select
and install updates.

However, after I upgrade to 14.10, when software updater's icon appers
in the launcher, it is unresponsive to clicking. While the icon is still
there, attempting to launch a fresh copy of Software Updater from the
Dash will not work, as there an instance of update-manager already
running (it's actually sleeping). It is only when I manually quit the
update-manager (right clicking on the icon and then click "Quit" will
do) that I can relaunch Software Updater.

Curiously, after relaunching Software Updater in this case, it will
forget about its previous window size, and default to the tiny version
instead.

This problem happens every time for me, so I'm not sure of the exact
circumstances under which  it's replicable.
