this should be fixed in trunk now [1] (this bug has been introduced
recently, it is not affecting releasebranch_6_3 at all). Can you
confirm it?

Any GRASS location should have valid information about projection.
Anyway it is not reason for crashing GUI. I will take a look.

It can be issue of wxPython version you are using.

Just enable auto-rendering (right-most checkbox in the map display statusbar).
