Created attachment 444242 [details] blank process list I was playing with VirtualBox, distcc and Gentoo no-multilib. After change to ~amd64 htop (2.0.2) stops working properly. After mask >sys-libs/ncurses-5.9-r99 and recompile, htop starts working again.

You probably need to recompile python against the new version of ncurses.
Sorry, I was thinking of iotop.
Should be no longer an issue. Reopen if I'm worng.
