** Description changed:

+ [Impact]
+ 
+ Notification area applet might crash when some apps with indicators support
+ send it some signals it doesn't know how to handle.
+ 
+ The patch attached to this report fixes the issue.
+ 
+ The fix is already present in Artful and tested by developers and users.
+ Would be nice to backport it to Zesty as well, as the bug makes notification
+ area unusable.
+ 
+ [Test Case]
+ 
+ Just install and run psensor, should be enough to trigger the crash.
+ Might need baremetal system for it, not guaranteed to be reproducible in VM.
+ 
+ [Regression Potential]
+ 
+ None. The patch just replaces assert (i.e. app abort) with a debug
+ message.
+ 
+ [Other Info]
+ 
+ The patch is included into the debdiff attached to bug 1675888.
+ 
+ The debdiff contains patches to fix bug 1675888, bug 1676840, bug 1690517,
+ bug 1695648. See other reports for the corresponding SRU templates.
+ 
+ Note that the debdiff attached to bug 1690517 is a separate one for
+ Artful.
+ 
+ [Original Description]
+
