Maybe this came from a plugin 'ez-on-da-ice'. After uninstall this, file chooser worked correctly.
Comment 3 NeilCSmith 2012-07-11 14:15:22 UTC 
This is called by a bug in o.n.swing.dirchooser  This module caches the first installed UI for JFileChooser, and doesn't respond to look and feel changes later.  On Java 7 / Windows 7, the DelegatingChooserUI continues trying to use the WindowsFileChooserUI despite the look and feel being replaced.  On Java 7 this causes a NPE, though not with Java 6.

Workarounds are to set '--laf Metal' or '-J-Dstandard-file-chooser=true' in the .conf file.

Noticed this in Praxis which uses NimROD look and feel, just like ez-on-da-ice.
