I happened to close the dialog window that displays load warnings when I open a file (because of say, bad parameter references) - is there a place I can query those load warnings from python? Or perhaps, are those errors logged to somewhere?

Ultimatly I'd like to build an interface to help jump to those nodes and paramaters that are in error so I can fix them. It would be mildly helpful if you could select the text in the open dialog so you could at least cut and paste your way there. Smells like RFE.
