Problems with Finder preview column and get info dialog

Hi. Last week I installed the Mac OS X 10.4.3 update, the Java thing, and the Airport patch. I have experienced two problems since then. I believe they are related.

The first problem can be observed in the Finder and Open File dialogs: if I select any file in column view mode, the cursor changes to a beachball and the application locks up.

The second problem occurs when I do Get Info on a file: the cursor changes to a beachball and get info locks up.

Both problems occur on any file type under any path.

Here is the (full) output from running "sample Xcode 10" from the terminal, after Xcode locked up in an Open File dialog.
