Bug in freetype2 2.6.2-1?

Hi,

I'm creating a simple graph with graphviz and export it to a pdf file. When viewing this pdf with evince, the node labels cannot be displayed. The log of evince contains the very descriptive error message "some font thing failed" multiple times. After downgrading freetype from 2.6.2-1 to 2.6.1-1, the fonts can be displayed succesfully. I'm not sure if this is really a freetype2 problem, which is why I don't want to file a bug report at the moment. Here is some trouble shooting information to reproduce the problem (minimal arch installation to pin down the problem):

Explicitly installed packages:

base
base-devel
evince
gptfdisk
graphviz
i3
rxvt-unicode
syslinux
xorg-server
xorg-xinit

test.dot:

graph {
  a -- b;
}

Compiling the dot file:

$ dot -Tpdf test.dot -o test.pdf -v
dot - graphviz version 2.38.0 (20140413.2041)
Using render: cairo:cairo
Using device: pdf:cairo:cairo
libdir = "/usr/lib/graphviz"
Activated plugin library: libgvplugin_dot_layout.so.6
Using layout: dot:dot_layout

Downgrading freetype2 (remove url tags added by FluxBB):

$ curl [url]https://archive.archlinux.org/packages/f/freetype2/freetype2-2.6.1-1-x86_64.pkg.tar.xz[/url] > /tmp/freetype2.pkg.tar.xz
$ pacman -U /tmp/freetype2.pkg.tar.xz

As mentioned before, after downgrading everything is fine, evince can display all the node labels without any problem and I cannot see an error message indicating that "some font thing failed". Can anybody confirm this? Is this a freetype2 bug?

Best
