Hi experts.
I use sagemath 4 months ago. Now, when i louch any .sage file this appears:

Saved trace to /home/joseluismietta/.sage/crash_logs/sage_crash_H411aN.log
Unhandled SIGSEGV: A segmentation fault occurred in Sage. This probably occurred because a compiled component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this.
Sage will now terminate.

What can I do for fix it?
Please help.
Thanks a lot
