importwallet method is working or not? #3670

When I try use importwallet method bitcoind always crash. Compiled from latest git sources (Bitcoin version v0.9.0rc1-47-g6056c87-beta).

*** glibc detected *** ./bitcoind: free(): invalid pointer: 0x00007fd11a766200 ***

I can reproduce this. I've exported a wallet using dumpwallet and try to import it with a fresh wallet.dat, and I get a long error message from glibc.

See #3691 for fix
