Here's a test case you can copy and paste into your codebase! When it passes, this bug is fixed.

import com.intellij.openapi.fileEditor.FileEditorManager;
import com.intellij.openapi.fileEditor.FileEditorManagerAdapter;
import com.intellij.openapi.vfs.VirtualFile;
import com.intellij.openapi.vfs.ex.dummy.DummyFileSystem;
import com.intellij.testFramework.IdeaTestCase;

public class FileEditorTest extends IdeaTestCase {
  public void testDummyFileEditorManagerFiresEvents() throws Exception {
    VirtualFile root = DummyFileSystem.getInstance().createRoot("root");
    VirtualFile textFile = root.createChildData(null, "ok.txt");
    FileEditorManager editorMgr = FileEditorManager.getInstance(getProject());
    final VirtualFile[] opened = {null};
    editorMgr.addFileEditorManagerListener(new FileEditorManagerAdapter() {
      public void fileOpened(FileEditorManager source, VirtualFile file) {
        if (opened[0] != null) {
          fail();
        }
        opened[0] = file;
      }
    });
    editorMgr.openFile(textFile, false);
    assertEquals(textFile, opened[0]);
  }
}
