Comment 4 for bug 1807621

this bug hit my inbox; so I booted 18.10 on x86 & tried it

guiverc@dx6120lu:/de2900$ qpdfview Firearms-Act-1996-v.64.pdf
Icon theme "breeze-dark" not found.
Segmentation fault (core dumped)

guiverc@dx6120lu:/de2900$ apt-cache policy qpdfview
qpdfview:

The pdf i tried to view was the first I found. It was opened successfully using the same command on my 19.04 x86_64 box (using 0.4.17~beta1+git20180709-2 [typed in, not copy/pasted])
