What I did was...
1) Go to Folder Properties
2) Find "Folder with Files" or whaddayacallit ("Папка с файлами" in Russian)
3) Added a custom action (Open in Terminal)
Now whenever I try to open a folder, it doesn't open it, but instead launches the "Find" thingy which searches for files, for the selected folder. I need to recover it to normal. Please, help!
