[issue22599] traceback: errors in the linecache module at exit

Maybe we can always ignore non fatal errors when calling linecache
from print_exception? Having the Python source code in the traceback
is better, but it's easy to get it because the filename and line
number is always present.

Maybe the linecache module can provide a better exception than the
current AttributeError?
