Thread Dump showing deadlock

For a few days now, I've been facing a rather annoying problem: I choose a Swing form (JFrame, JDialog, JPanel) in the Projects tab, and then I open it using the "Edit" menu. After looking at the source code of the form for a bit, I click the "Design" button to have a look at the GUI. The form never loads, as the IDE freezes completely. This seems to be completely random, I can't find a way to reliably reproduce it.

I tried monitoring NB using JVisualVM and saved a thread dump after the IDE froze, JVisualVM identified a deadlock. The thread dump is attached to this report. I also saved a heap dump, but I don't know if I should attach it, since it's way too big (~86 MB uncompreesed, ~19.5 MB compressed) and I don't know if it's relevant to diagnose this problem. My setup is as follows:

Product Version: NetBeans IDE 6.9.1 (Build 201007282301)
Java: 1.6.0_21; Java HotSpot(TM) Client VM 17.0-b17
System: Windows XP version 5.1 running on x86; Cp1252; en_BR (nb)
