Hi,
I facing a somewhat similar issue. I transferred bitcoin to bitshares and now I cannot withdraw it. I keep getting the following error:
Failed to broadcast the transaction:bitshares-crypto digest b4ab1762005dbc11066ace9e3c24fd3a99b3ec02db53842b99e9973ccf57f4ff transaction e8758f56fad5d9286b590100185b00000000000000a6cd168df10575b9d10100000000dd0601036ad58020cae68f13c862de6a6b259a3804399e6c554f4bc22de4deb5cc2c070e0208572ee1329408ef4652cccbfc14257dc39649d1f0194e6efa2eeab41c3f7da4cc27dd974a5d01003063449924c6e60df3a74f37852511793c34cc8035fcd92bf76d45488a1068d963b565b435080ae72593a8af83f1313f530000 {"ref_block_num":30184,"ref_block_prefix":3589953167,"expiration":"2017-07-16T08:50:33","operations":[[0,{"fee":{"amount":"23320","asset_id":"1.3.0"},"from":"1.2.370342","to":"1.2.96397","amount":{"amount":"30521717","asset_id":"1.3.861"},"memo":{"from":"BTS7eHTgYFpuNRUYR8kK7jDQLmcTM1h8EzNjuMKj8n6GnNsudW2jX","to":"BTS4xAQGg2ePLeDGZvQFpsh9CjMhQvRnVkPp6jPoE6neVPotRfZX9","nonce":"384049933526988","message":"63449924c6e60df3a74f37852511793c34cc8035fcd92bf76d45488a1068d963b565b435080ae72593a8af83f1313f53"},"extensions":[]}]],"extensions":[],"signatures":["1f2b720caed72cb6e4a390b1ecd03fefbfbe6c03418da32a828fab3c67f55c56d028f9a6914f922a83a049bc1e448ebd07341019f38b39873b06aa3ab5e55bebc5"]}
