+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.
