I had apt installed from experimental ( I did not know until Axel told
me at #7944269)

But now i have apt installed from unstable, and i purged cupt and
installed again, and it is giving me segmentation fault.

At gdb:

Program received signal SIGSEGV, Segmentation fault.

const*> >::get (this=this at entry=0xfc5268)

I hope this help

Thank you very much
