+Subject: [PATCH] Guard against NULL 'base' for non-clist devices
+
+Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
+
+This is actually for the plib device. This device is currently (this will
+change in the next commit) set to BandingAuto, despite the fact that the
+device only works in banding mode.
+
+This can lead to use arriving in gdev_mem_open_scan_lines with all of
+mdev->bitmap_memory, mdev->line_pointers_memory and mdev->base being set to
+NULL. The code didn't check and assumed that mdev->base was valid, which
+led to a later seg fault.
+
+Here we just check to make sure it isn't NULL and return an error if it is.
+This doesn't prevent the possibility of garbage uninitialised values, but
+there's not much we can do to check that at this stage, devices are supposed
+to be initialised to 0 so this 'shouldn't' happen.
+
+No differences expected.

+Subject: [PATCH] Ensure plib devices always use the clist
+
+Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
+
+the plib* class of devices only work if clist is present, but previously
+they left the banding_type set to 'auto', which meant that under some
+conditions we did not use the clist, leading to a seg fault.
+
+This commit simply forces banding_type to be 'BandingAlways'.
+
+No differences expected.

+Subject: [PATCH] prevent rinkj device crash when misconfigured (no SetupFile)
+
+Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
+
+The rinkj device requires a SetupFile to be given as a device parameter,
+however it doesn't actually check to see if one is given, and just tries
+to open the filename, with a predictable crash when none is given.
+
+Here we check the filename and attempt to ensure it is both present and
+minimally valid.
+
+No differences expected.
