Matlab segfaulting now. A few weeks ago, dont. Maybe a bad upgrade...

[Paulo Henrique Baptista de Oliveira <baptista@cos.ufrj.br>]

    Hi Debian users,
    At home and school I have matlab installed in Linux 2.1 or 2.2 very
synced with potato. Sometime ago was working in both. Now it's only
working in school. Maybe I did an upgrade in school different from home.

At home I have:

    Thanks for any info. I have to do a homework in one week using
Matlab.
    Have a nice day,        Paulo Henrique
