[bitbake-devel] [PATCH 4/8] ui/hob: show error and exit if we receive the fatal-error signal

[Joshua Lock]

If we receive the fatal-error signal from the handler display a dialog
informing the user of an error and displaying the error message. Dismissing
the dialog quits the application.

Fixes [YOCTO #1279]
