Problems with Trezor setting in Electrum 2.6.4 under Ubuntu Linux 14.04

[Bit_Sig]

Hi Thomas,

First, thank you for the great Electrum product!

Can you please advise on the fixing the problem with setting up Trezor with Electrum 2.6.4 under my 64 bit Ubuntu Linux 14.04. I installed the latest Electrum 2.6.4 from your web site easy installation option and tried to set up Trezor with it but failed. Every time when I connect Trezor, then in Electrum check Create New Wallet and then Hardware Wallet and on the next screen push Next to go to selecting the type of hardware wallet, I receive "list index out range" error and Electrum collapses. Thank you.
