Failed to restore wallet backup. Your original wallet has been restored. Error: Assert Exception (10) v.size()<= sizeof(fc::ripemd160) + 4 :all addresses are less than 24 bytes
invalid address 'BTSXsQYmnwKxzV6gBbWv1Y2fXCqACXrS6FgU'

I first updated the client without cleaning the database.
One of my account can't list the balance . But the historical transfers of this account is correct.
So I cleaned up the database and sync again.
When I attempted to import my wallet backup got this error.

By the way my system is ubuntu

Our team menbers are ebit and me. We are from china. First please forgive my poor English below

We are committed to participate in everything related to the promotion and Btsx system and re-development activities. Not limited to the following we have undertaken.

Promot Btsx.
Help each one who want to be a delegate, who want to contribute to the stability of the Btsx system.
Now Btsx 101 active delegates has been stabile.  However system security and stability requires more obscure standby delegates to make the system more safty and stable. But the rules have been decided delegates after 101 have no incomes.

The delegates need to stand the cost of renting servers. Standby delegates need to always be concerned about the official release of the new versions of the clients to update the delegate client. Also should give a lot of assets (bitUSD, bitCNY, bitBTC etc.) feed prices and make sure that the standby delegates and the active delegates have the same standard.

For these reasons above, I initiated a event for standby delegates giving some feedback (FUND assets) as award in chinese community.

FUND asset will play a greater role on interaction between the active delegate team and standby delegates. Let's  look ahead.

We will donate our delegates' income 10% to FUND asset & 10% to standby delegates.

We are running two delegate accounts on separate servers . one in Shanghai another in Zhengzhou.

Delegates Account Name: she.bitrose和btsx.outofcontrol
All 80% payrate.

wallet_account_set_approval btsx.outofcontrol true
wallet_account_set_approval she.bitrose true

为了更好的奖励像btsx.outofcontrol一样的standby待命受托人，也为了鼓励广大btsx玩家为这些standby待命受托人投票，在此开展fund资产派送计划。

众所周知只有获得票数最多的101个受托人有btsx出块奖励。
很多默默为btsx网络安全做出保障的待命受托人和其他受托人一样及时更新版本，宣传btsx，参与社区各种活动宣传问题讨论。
在这里我将利用ebit最新创建的fund数字资产奖励这些和本人一样时刻坚守在standby前线的btsx玩家。

规则：回帖告诉我你的曾经、现在或者将来会standby待命受托人ID，我将给予大量fund 资产奖励，同时投票给你们。

为了让我们更好的standby下去，让我们共同努力携手把我们standby的ID喊出来，让社区来知道我们，奖励我们为btsx做出的贡献~

感谢ebit众筹了fund资产为本活动提供的帮助
