These are the current limits:

ciaby@lila:~$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 23805
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 95
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 23805
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Max locked memory is set to unlimited, so that's not the problem here.
I'm currently rebuilding the latest package with this line:

    got_secmem=secmem_init( 262144 );

Instead of this line:

    got_secmem=secmem_init( 32768 );

I'll let you know in a bit if it fixes the problem.

  gpg: out of secure memory while allocating 2048 bytes
  gpg: (this may be caused by too many secret keys used simultaneously or due to excessive large key sizes)

  Obviously, the latest security patch breaks ElGamal encryption with large keys (in this case, 16384 bytes).
  Although GnuPG doesn't allow to generate these keys, the PGP standard (and GnuPG itself) supports large key sizes.
  Please review the latest patch and make sure that all key sizes are supported.
