libpurple2.5.2 crash when add buddy

[yyaadet2002]

Hi, all:

my codes here :


static void im_blist_request_add_buddy(PurpleAccount *account, 
const char *username,
const char *group, 
const char *alias)
{
const char *grp, *who, *whoalias;
PurpleGroup *g;
PurpleBuddy *b;
PurpleConversation *c;
PurpleBuddyIcon *icon;
who = username;
grp = group;
whoalias = alias;
if ( whoalias == NULL || *whoalias == '\0')
whoalias = NULL;
g = NULL;
purple_debug_info(__func__, "Account %s, username %s, group %s, alias %s\n", \
account->username, 
username, 
grp,
alias);
if(grp == NULL) {
if( NULL == (g = purple_find_group("friends"))) {
g = purple_group_new("friends");
purple_blist_add_group(g, NULL);
}
} else if ((grp != NULL) && (*grp != '\0') && ((g = purple_find_group(grp)) == NULL)) {
g = purple_group_new(grp);
purple_blist_add_group(g, NULL);
}
assert(g);
b = purple_buddy_new(account, who, whoalias);
purple_blist_add_buddy(b, NULL, g, NULL);
purple_account_add_buddy(account, b);
/*
 * XXX
 * It really seems like it would be better if the call to
 * purple_account_add_buddy() and purple_conversation_update() were done in
 * blist.c, possibly in the purple_blist_add_buddy() function.  Maybe
 * purple_account_add_buddy() should be renamed to
 * purple_blist_add_new_buddy() or something, and have it call
 * purple_blist_add_buddy() after it creates it.  --Mark
 *
 * No that's not good.  blist.c should only deal with adding nodes to the
 * local list.  We need a new, non-gtk file that calls both
 * purple_account_add_buddy and purple_blist_add_buddy().
 * Or something.  --Mark
*/
c = purple_find_conversation_with_account(PURPLE_CONV_TYPE_IM, who, account);
if (c != NULL) {
icon = purple_conv_im_get_icon(PURPLE_CONV_IM(c));
if (icon != NULL)
purple_buddy_icon_update(icon);
}
}
