Shift + Key creates unknown event in SFML 2.3

[Orfby]

I recently upgraded from SFML 2.2 to 2.3.2, and at first the upgrade seemed seamless, with no compiler errors. But I discovered I couldn't open my console (Which is opened with 'LControl + LShift + C'). After doing some testing it seems like inputting a key on its own (A, B, C etc.) gives the expected key code, but inputting shift and a key gives an unknown key code. I know this bug was  reported a few years ago but since it worked in the previous version I don't know why it would be broken again. I'm using Ubuntu 14.04 (Linux) and the problem occurs with both my normal keyboard and the on-screen keyboard.

EDIT

Only just saw this, I can try to compile SFML myself but I have no experience with it

You can also download the released version 2.3.2, it's already better than 2.3.

What keys are concerned? Shift + any key?

I'll try to download 2.3.2, assuming 2.3.2 isn't the first recommended one, otherwise I already have it
EDIT: I do have 2.3.2, I just checked and the file is called "SFML-2.3.2-linux-gcc-64-bit", sorry I wasn't more specific in the first post.

Almost all keys are concerned, the only ones that aren't are Divide, Multiply, Minus and Plus on the numpad, as well as all Return keys and the function keys. But all the alphanumeric keys are affected
