+Subject: [PATCH] Avoid crash on toc.ncx navPoint without navLabel
+
+Althoug at least one navLabel is required per navPoint, there is no
+guarantee it actually exists.
+
+Avoid crashes due to invalid accesses of a null label in case the toc is
+broken, and spew a warning.
+
+Fixes #8 epub_tit_next crashes on navPoint without navLabel.
