blockchain.info wallet: can't import wallet with watch-only addresses?

[Kazimir]

When exporting a wallet that holds a regular address (+private key) and a "watch-only" address (without private key), I might get something like this:

Code:

{
	"keys" : [
{"addr":"13K3zuiG4GshxQQWhYL1rYn89Fg14nqnQn","priv":"5KkcNPnZdMY18QXrfhdxBqNMVauGQLPBvHxuBzNaa5DQELU8V2R"},
{"addr":"13GZ21RbYqEz71dgRRkWwnoQ6DTBcXhiK9"}
	]
}

However, I can't import this. Well I can, but it seems to ignore the watch-only address. When I remove that private key, thus only importing watch-only addresses, it says "Unknown Format Incorrect Password".

Now of course for single addresses I can re-add them manually, but I've also got wallets with 30+ watch-only addresses where this would be a nuisance.

Is there a workaround for this?
