Comment (by aschilling):
Hi Volker,
Ok, I can reproduce the error now. But how are we supposed to fix it? Here
are three scenarios and none of them work:
{{{
sage: from sage.combinat.sf.new_kschur import kSchur
sage:
sage.structure.sage_object.register_unpickle_override('sage.combinat.sf.kschur',
'kSchurFunctions_t', kSchur)
sage: sage.structure.sage_object.unpickle_all()
* unpickle failure:

or the next even crashes Sage:
{{{

sage:
sage.structure.sage_object.register_unpickle_override('sage.combinat.sf.kschur',
....: 'kSchurFunctions_t', kSchur.Element)

sig_error() without sig_on()
------------------------------------------------------------------------
Unhandled SIGABRT: An abort() 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().
Sage will now terminate.
