Finder: Cannot open a certain folder in list or coverflow view (OS9 folder, maybe polluted legacy?)

Question

PROBLEM SUMMARY:
I observe a very strange Finder bug (already in 10.5, and still now in 10.6), which only occurs within one specific folder with certain Finder view modes (list, coverflow).
ATTEMPTED SOLUTIONS & SPECULATION:
I already tried everything to fix it, both by GUI and CLI means, such as recursively setting file/folder permissions to default values, erasing .DS_Store and Icon files, etc, but nothing helped so far. The troubling folder and its contents (files and subfolders) is quite old, created still while OS Classic days, maybe it contains some "bad legacy / leftovers", like deprecated filesystem flags or resource forks, which cause the trouble.
PROBLEM DETAILS:
This is the directory structure:
~/Documents/Songs:
   /Composing
   /Final
   /Patches
   /Web
All folders can be accessed in any view mode without any troubles, except "Composing".
If the parent folder "Songs" is set to icon or column view mode, then "Composing" can be opened.
But in list view (my default view), or coverflow, the opening action, regardless wether via mouse double click or keystroke CMD-ArrowDown, causes no update of the window content. The window content remains in a flawed look and responseless state, only closing or using the return-navigation on the toolbar UI area puts the window content into a correct and reactable state again, or opening a new window and navigating to "Songs" again.
The time-correlating message to this error in the Console.app log reads:
Finder *** -[NSCFArray insertObject:atIndex:]: index (9) beyond bounds (9)
Interestingly: If you are within "Songs" using the list view, collapsing the folder "Composing" via the triangle symbol successfully renders the folders content, and you can navigate further down in the hierarchy with the collapsing method, and even double-click subfolders, which then open normally in list view. Just "Composing" itself shows this mysterious bug.

Answer 1

Maybe some of the invisible .DS_Store files in your folders are corrupt.
Launch your Terminal and paste the blue code below into it.
Press Return and type in your password - press Return again and wait for the word 'done.' to appear.
Then quit the Terminal.
sudo find / -name \.DS_Store -exec rm -fP {} \;;echo done.
Next, relaunch the Finder - press Command Option - click and hold down the Finder in your Dock and select Relaunch.
Good luck,
Tom
