sage crash on osx 10.6

[john_perry_usm]

Hi,

A student encountered an error when running sage from the command line
on OSX 10.6. When she tries the command

sage: point((3,3))

sage crashes and OS X gives the message,

/Applications/sage/local/bin/sage-sage: line 199: 5436 Abort trap
sage-ipython "$@" -i

sage does not crash when creating a point, only when trying to show
it, and only from the command line.

In Linux, this works fine, and I realize this is OSX so maybe it
shouldn't work at all. She didn't try it before upgrading to 10.5, so
we were wondering if

(1) this is expected behavior;
(2) if not,
(2a) does anyone else encounter this problem on OSX, or is her
computer bonkers?
(2b) is there a possible fix? that is, is there a missing program that
sage is trying to call, but failing & thus crashing, so she can fix
this by installing the program?

regards
john perry

This works fine for me in both 32 and 64-bit OS X 10.6. I.e., it
definitely doesn't crash for me.

Does the student have fink or Darwin Ports installed? Is there a /sw
directory? Is /usr/local/ full of crud? That's my guess.

I vote for bonkers :-)

Sage just calls OS X's "Preview", which is standard (it's part of OS X).

Crap. :-)

No, no, not sure. I'll have to check her /usr/local, but it's a
relatively new Mac and she hasn't even heard of Darwin Ports or fink.
(I have, so I think I see what you're saying.)

She does, too. She has had other problems with her computer since
installing 10.6. (OSX claims that Lyx crashes seemingly randomly, for
example, although Lyx does not in fact crash.)

It isn't a big issue, so I won't worry about it unless someone else
also has this problem.

thanks though.
