strange, i rewrote the function to have a better overview, one file i can
close the other not.


gboolean crypto_mapper_check(gchar *data)
{
   gchar *mapper_chk_cmd;
   gboolean result_mapper=FALSE;

   mapper_chk_cmd = g_strdup_printf("/dev/mapper/%s", data);

   FILE *fp = fopen(mapper_chk_cmd, "r");
   g_free(mapper_chk_cmd);

   if(fp)
       result_mapper = TRUE;
   else
       result_mapper = FALSE;

   //fclose(fp);    /* this one crashes the the app when enabled*/
   return result_mapper;
}

# define MOUNT_PATH "cat /proc/mounts|grep %s"

gboolean crypto_mount_check(gchar *data)

   gchar *mount_chk_cmd;
   gchar buf[512];

   mount_chk_cmd = g_strdup_printf(MOUNT_PATH, data);

   FILE *pp = popen(mount_chk_cmd, "r");
   g_free(mount_chk_cmd);

   if(pp) {
