The default glabels-3.4.x install on Fedora 25 through 29 segfaults when using the glabels-3-batch command. The following command fails:

glabels-3-batch -o output.pdf -i crossdock-data.csv 150x200-crossdock-labels.glabels

I found compiling from source with defaults and it doesn't segfault. However I found if you download the src.rpm and just run a straight build from it the segfault still happens.

So to get a working copy of gLabels on Fedora 25 - 29

# remove glabels
dnf remove glabels-*
# install the build dependencies
sudo dnf builddep glabels-3.4.0

Download and extract http://ftp.gnome.org/pub/GNOME/sources/glabels/3.4/glabels-3.4.1.tar.xz

cd glabels-3.4.1/
./configure 
make sudo make install 
# installs to /usr/local

And now try glabels-3-batch
