Comment (by oliver):

 Another one:

 73 bytes in 1 blocks are definitely lost in loss record 587 of 1,585
    at 0x4020AA4: calloc (vg_replace_malloc.c:279)
    by 0x412122D: g_malloc0 (in /usr/lib/libglib-2.0.so.0.1200.11)
    by 0x4AA56AA: msim_process (myspace.c:480)
    by 0x4AA5F8A: msim_input_cb (myspace.c:1258)
    by 0x8058126: purple_glib_io_invoke (libpurpleinit.c:53)

 i guess we wont need "data" after it is encrypted at myspace.c:487
 (purple_cipher_context_encrypt() ) and can destroy it before rturning.
