+Subject: zathura-pdf-mupdf: Link to JPEG libraries.
+
+As of version 0.3.3, zathura-pdf-mupdf no longer links to some required
+JPEG libraries, leading to such errors as:
+
+  $ zathura foo.pdf
+  error: Could not load plugin '/gnu/store/...-profile/lib/zathura/libpdf-mupdf.so' (/gnu/store/...-profile/lib/zathura/libpdf-mupdf.so: undefined symbol: jpeg_resync_to_restart).
+
+The patch below, copied verbatim from Arch[0], fixes that.
+Its description happens to match our reality, too.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Normally these are statically linked into libmupdfthird, but we delete
+those to make mupdf use the system libraries.  Previously
+zathura-pdf-mupdf explicitly linked against them, but this is
+technically incorrect since they are supposed to be in libmupdfthird so
+that was removed.  This commit essentially reverts that in the new build
+system.
