$ bitcoind sendfrom '' a1 1
error: no response from server

I compiled with debugging, and it crashed on an assert() in bash58.h:
#2 0x00000037510296e6 in __assert_fail () from /lib64/libc.so.6

Do we need to check address.IsValid() in rpc.cpp before calling SendMoneyToBitcoinAddress()?

I think other RPC calls which take an address have the same problem too.
