Comment (by SimonKing):
Ooops! That's odd:
{{{
sage: s = ModularSymbols(11).2.modular_symbol_rep()[0][1]
sage: f, (a,b,c), D = s.__reduce__()
sage: s = ModularSymbols(11).2.modular_symbol_rep()[0][1]
sage: D['_ModularSymbol__space']
Manin Symbol List of weight 2 for Gamma0(11)
sage: s = ModularSymbols(11).2.modular_symbol_rep()[0][1]
<BOOOM>
}}}
So, printing the "Manin Symbol List" is enough to trigger the crash. Very
bad.
