I took a quick look at the 6.3 error message. Can I make a couple of suggestions?
1. Instead of "Error creating new location from EPSG code. g.proj returned following message:" replace with "Unable to create new location from the EPSG code xxxx provided in the input box [or whereever it came from]. The module that creates new locations, g.proj, returned the following message;" 2. Put the message from g.proj into double or single quotes and have it not break at strange places. 3. Add a list of possible sources of the problem. I guess these might be an invalid path or a typo in the EPSG number. There's probably better ways to do this than my suggestions.
