-Bug 699665 "memory corruption in aesdecode"
-
-The specimen file calls aesdecode without specifying the key to be
-used, though it does manage to do enough work with the PDF interpreter
-routines to get access to aesdecode (which isn't normally available).
-
-This causes us to read uninitialised memory, which can (and often does)
-lead to a segmentation fault.
-
-In this commit we set the key to NULL explicitly during intialisation
-and then check it before we read it. If its NULL we just return.
-
-It seems bizarre that we don't return error codes, we should probably
-look into that at some point, but this prevents the code trying to
-read uninitialised memory.
