WordPress support

So, I’m still trying to figure out how to get the plugin installer for WordPress to actually list some plugins (currently, it only shows “A” and no plugins).  I probably have the filesystem permissions locked down too tightly, but it’s just annoying that nothing prints a debug message or anything.  I’ve got a post on the support forums at http://wordpress.org/support/topic/258531 looking for an answer, but I’m not holding my breath…  Help would be appreciated. :)
