  +Subject: [PATCH 2/2] Keep multiple system keyboard layouts for session
  This patch contains one serious bug:
  ++                config->layouts = g_new0 (char *, g_strv_length (initial_config->layouts) + 2);
  ++                config->variants = g_new0 (char *, g_strv_length (initial_config->variants) + 2);
  In case you have 2 layouts and variants are not specified (I got that scenario), you will allocate 4 and 2 elements correspondingly. This is clearly wrong - because later you'll assign 3 variants. Then gdm-greeter crashes inside xklavier (memory corruption).

  The correct code should have
   config->variants = g_new0 (char *, g_strv_length (initial_config->layouts) + 2);

  This is gdm crasher, so please fix it ASAP.
