Got the same problem. All of my other wallets will consolidate the inputs but Electrum is a pain. It broadcasts the output as 200 inputs which screws me every time. About to quit using Electrum. I can send 200 inputs to Blockchain and it will transfer it with no problems. Electrum gives me the dust error, and the we wanted more fees error. Electrum is CRAP!!! I tried to send a transaction with a 10% fee today and it still failed. What a load of crap!!!
