The problem here is the import of the gtk module which was just introduced with the addition of the magnification settings support.  Rich, a way around this is to wrap the import and use of gtk stuff in try/except blocks.

orca --text-setup is still crashing for me, now with the following output:

Comment 5 Rich Burridge 2006-05-05 00:01:18 UTC

Reopening the bug. I'll investigate further tomorrow.

Comment 6 Rich Burridge 2006-05-05 00:04:23 UTC

Arrgh! It was a cut and paste error. Line 40 in settings.py
needs to be changed from:

screenWidth = 480

to

screenHeight = 480

Al, if you are in a position to try this before tomorrow,
I'd appreciate your feedback, otherwise, when I get in the 
office tomorrow and fire up my development computer, I'll
fix it up then and check it in.

Thanks.
