Finder folder icons look like document and image files

I've got an annoying issue for a couple of weeks now. My folder icons got corrupted from time to time:

Left side is the view I get when I'm switching between views, but when I open finder or navigate to a folder I see its content as on the right side of the image. When I have multiple files and subfolders in a folder, icons of the folders appear as icons of images, and documents around them...

I have the latest updates and I've never used any app that customises Finder.

Has anybody experienced something similar?

Update: I have Tuxera NTFS 2012.3.4 and OSXfuse 2.5.4 installed. Removing OSXfuse and disabling Tuxera doesn't affect this behaviour.

Update: Same behaviour with OSX 10.8.3

Solution 1:

Try resetting the Launch Services database. Dig into your Utilities folder and paste this into Terminal:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user

You may need to restart the Dock and Finder to see if it's worked:

killall Dock; killall Finder

Alternatively, just reboot after you've reset the Launch Services database.
