+# Work around a bug in Slackware's ghostscript.
+# http://bugs.ghostscript.com/show_bug.cgi?id=692891
+#
+# Supposedly this was fixed, but I'm getting stack traces that look just
+# like those. The trouble is, if any of the plugins depends on libgs.so,
+# that library gets loaded during zathura's "scan for plugins" phase.
+# If libjpeg.so wasn't already loaded, it gets loaded and mangled by
+# libgs. This happens *before* zathura knows which plugin matches the file
+# we're trying to view. Now, the plugin is chosen based on the file's
+# mime type. If said plugin *isn't* the one using libgs, but it *does*
+# use libjpeg, *boom* segfault.
+#
+# What I found is that the postscript plugin uses libsceptre, which uses
+# libgs... and the mupdf and comicbook plugins use libjpeg.  The end result
+# is that the mupdf and cb plugins crash the first time they try to load
+# a jpeg from the pdf/cbr, *but* only if the ps plugin is installed!
+# Both plugins work fine if the ps plugin is removed.
+#
+# I found that 'export LD_PRELOAD=/usr/lib/libjpeg.so' stops the
+# segfaulting, while not affecting the ps plugin. The patch below is
+# basically just the C equivalent: use dlopen() to load libjpeg.so before
+# scanning for plugins. Yes, it's a hack, that depends on implementation
+# specific details, but the alternative would be to try and talk Pat V
+# into patching and rebuilding his ghostscript and/or libsceptre packages,
+# which he won't be doing this late in the release cycle (I wouldn't either).
