Just updated Arch Linux with the following packages:
pyqt5-common 5.6-1
python2-pyqt5 5.6-1
And now calibre fails to launch, with the following error. Reverting those two packages to 5.5.1-2 fixes calibre:
[eschwartz@arch ~]$ calibre
calibre 2.57.1.r17.g9d46a5a embedded-python: False is64bit: False

('Linux', '4.5.5-1-ck', '#1 SMP PREEMPT Tue May 24 20:03:35 EDT 2016')
Python 2.7.11

Actually, as it turns out I just needed to rebuild calibre. Sorry for the noise.
