A pay to multiple addresses feature is broken

[VasiliPupkin256]

I've tried to split my coin by sending some fractions of it to my other change wallets. So I've typed:
<mywallet1>, 3
<mywallet2>, 3
<mywallet3>, 3
into the "Pay to" field and got an error "Failed to create a transaction, you've found a bug please contact devs"

Can you paste the full error message?

I've also found that this is only happening if one of the address is in "integrated" form (starting with 4) while others are standard (starting with 8).

Ah, the protocol does not support this. I will close this issue when I've added a proper error message.

I've found a page on getmonero.org that say quote

Single transaction cannot pay to multiple integrated addresses

But can you mix a single integrated address with a standard one in a single transaction? It is not clear. But ok, a proper error message would solve the issue.
