+Subject: [PATCH] Bug 707264: Fix tiffsep(1) requirement for seekable output
+ files
+
+In the device initialization redesign, tiffsep and tiffsep1 lost the requirement
+for the output files to be seekable.
+
+Fixing that highlighted a problem with the error handling in
+gdev_prn_open_printer_seekable() where closing the erroring file would leave a
+dangling pointer, and lead to a crash.
