** Summary changed:
- fwbuilder crashes in Noble when trying to create almost any type of new object
+ [SRU] fwbuilder crashes in Noble when trying to create almost any type of new
object
** Description changed:
+ [ Impact ]
+
+ fwbuilder will crash immediately if the user tries to create almost any
+ type of new object.
+
+ On Noble, even the gnome-shell will crash when fwbuilder crashes and the
+ user will need to login again.
+
+ [ Test Plan ]
+
+ 1. Open fwbuilder
+ 2. Close the Quick Start Guide,.
+ 3. Click on the "New Object" icon.
+ 4. From the popup menu, click on "New Library"
+
+ If the package is not fixed then it will crash immediately.
+
+ With the fixed package, it will open the screen with the New Library
+ editor.
+
+ [ Where problems could occur ]
+
+ It is an upstream patch and is just adding a NULL check before the
+ pointer is actually dereferenced. There is no other change in the code.
+ And, so the chances of a regression is very less for this change.
+
+ [ Other Info ]
+
+ Focal also has the same problem but this patch alone is not fixing the
+ problem with Focal. It will need more changes and it appears it will
+ need fixes in "qtbase-opensource-src".
+
+ [ Original Bug Description ]
+
To reproduce:
* start fwbuilder without any arguments
* click "New Object"
* click any type of object, e.g. "New Library"
* fwbuilder will segfault
