phantom error "error parsing XML: unbound prefix"

Question

The error "error parsing XML: unbound prefix" shows up on my main layout: main.xml when I first open Eclipse. To make the error go away, all I have to do is make a modification to the file, then undo it, then hit save (have to make a change in order to be able to save file and thus trigger the new syntax check).

My environment is:

Fedora Eclipse Platform
Version: 3.4.2
Based on build id:  20090211-1700

My target is Android API level 5.

The first time I saw the error I spent a long time trying to track down "the problem" but later realized there isn't really a problem, it's just a phantom error.

Who should I report this to?

Answer 1

This sounds like a bug with the ADT plugin for Eclipse. I'd first check if it's already filed; if not, go ahead and report it at b.android.com.
