Description Joshua Lock - Disabled 2011-07-22 16:40:54 UTC 
I'd enabled a layer in my testing which included bbappends for non-existent files and caused a parse error. The GUI just kept spinning regardless...

If I run the knotty with the same bblayers.conf:

$ bitbake core-image-minimal -n

The knotty (command-line) interface exits with an error in this situation. The GUI should report an error and if possible aid the user in diagnosing and fixing it.
Comment 2 Joshua Lock - Disabled 2011-07-28 15:13:50 UTC 
The solution I've come up with is to show the user a dialog telling them there's been an unrecoverable error and then showing the (often terse) error message from the underlying system. The dialog has an "Exit" button for the user to acknowledge the message and quit the program.
Comment 4 Joshua Lock - Disabled 2011-08-02 16:12:30 UTC 
Fix is merged and I've benefited from the change already.
