incomplete folders

[laurent.orseau@…]

In my planet cache folder, I had a planet sub-folder that was incomplete.
My folder hierarchy was then:
...\planet\300\4.2.4\cache\orseau\mred-designer.plt\3
and that ends here, the directory is empty, because of a "planet remove" of that package.

planet-manager crashes on loading with:
"""
procedure tree-stuff->row-or-false: expects 3 arguments, given 2: #<path:mred-designer.plt> "3"
"""

This is probably an MzScheme? internal error, since I couldn't find tree-stuff->row-or-false in you package.
Removing the "faulty" subfolders solved the problem though.
