Arch Linux

Description:
The recent update of a bunch of QT5 packages from 5.4.2 to 5.5.0 has caused some problems with Calibre.

Specifically, when I try to add an EPUB from the command line with "calibredb add" I get the following:

This application failed to start because it could not find or load the Qt platform plugin "headless".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

Pulled down the PKGBUILD to try recompiling but getting a compilation error.

Additional info:
* package version(s)
calibre 2.31.0-1
qt5-base (5.4.2-1 -> 5.5.0-1)
