I have a very stable setup with Ubuntu 16.04 running readonly from a USB drive. I install an environment including libftdi (via apt) and pylibftdi (via pip) from a script. Today the setup did not work, and I noticed that the new release of pylibftdi (0.17) was released today. The error message is simply "Bus error". Rolling back to 0.16.1.2 was not enough, but changing the installer script to install 0.16.1.2 by default, then rebooting and starting from scratch did work.

Anyone else experiencing the same?
