NetBeans IDE Dev (Build 200703280911) 1.6.0; Java HotSpot(TM) Client VM 1.6.0-b105 Linux version 2.6.17-10-386 running on i386 en_US (nb); UTF-8 The IDE freezed after doing a copy-paste in the files view. I copied a golden file and pasted the copy to the same folder, after which the IDE stopped responding. I don't have steps for reproducing though.

There is no Java support in the stacktraces at all.
The problem is that there is no "Folder recognizer" request processor thread. However without steps or at least logs[1][2] there is very little I can do to fix this bug. [1] Either messages.log to see some exception [2] Try to generate more with org.openide.loaders.level=100
