Deprecated - Drupal core

Hi all,

i have problems with the xml validation of my rss feeds.
If you click on the rss button in the navigation bar (firefox + explorer7) tring to add the following link: http://www.verdesperanza.net/news/?q=rss.xml

you'll display an error.

I tried to go to the feedvalidator.org to discover the problem in the sintax and it seems to be a problem at line 3

the result is:
line 3, column 0: XML parsing error: :3:0: xml declaration not at start of external entity

I dont know exactly why - but at a given moment, on a specific drupal 5 (1,2,3,4... no difference) site, on botton of most pages I see the "feed.png" icon TWICE: one with a correct and working link (xxx/?q=rss.xml) and another with a link to the homepage (xxxx/) - of course without feeds associated. When the "correct" link/icon is not present because not needed (as in urls like admin/build...) the *wrong" icon/link is always present.

cache.inc 5.3 uses:
db_query("DELETE FROM {%s} WHERE expire != %d AND expire < %d", $table, CACHE_PERMANENT, time());
5.4 uses:
db_query("DELETE FROM {". $table. "} WHERE expire != %d AND expire < %d", CACHE_PERMANENT, time());

Why the change in that direction when direct insertion of fields into SQL leads to SQL injection exposure? The old way is a good example to avoid SQL injection, to show the right direction for new developers, and to make a switch to prepare/execute easier.

I am using Drupal 6.x beta3. When a user creates a blog entry, and then an administrator edits the blog entry, the breadcrumb for the blog shows the creaters name, but links to the administrators blog page. Can someone please confirm that this is happening on another instance, so I can rule out my environment as the issue. Here is the code responsible for creating the breadcrumb, starting at line 104 of blog.module:

Noticed a regression where menu_block inside menu.module isn't getting called. Anyone know where a good starting point would be to debug this issue?

Hello,
I'm wondering if there is a way to use the drupal_add_css (or if there is an equivalent) for linking external CSS files. If I call drupal_add_css('http://foo/bar.css'), the import statement code is incorrectly generated as '@import "/http://foo/bar.css"'.

Thanks,
Reuben
