profile page is broken in 5.5.2!

Permalink
I just made a completely new, clean (no add-ons or additional themes) installation of v5.5.2 but the profile page is throwing the following error:
Fatal error: func_get_args(): Can't be used as a function parameter in /concrete/libraries/item_list.php on line 515

I deleted all add-ons and re-installed, same error.

Anyone else having this problem? (I can't believe I could be the only one!)
