Bug 37483 – portage crashed by unmerging files with "IOError: [Errno 21] Is a directory"

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Micha Glave 2004-01-07 08:23:49 UTC]

When starting "emerge clean" I got the following Error (see "Actual Results").

I asked google and found: 
http://mail.python.org/pipermail/python-bugs-list/2001-November/008535.html

so it was a common problem when changing from Python 2.1 to 2.2. Maybe depending on the Python-Version (I use 2.3.3)

Maybe It is just a failed dependency. 

Reproducible: Always
Steps to Reproduce:
1.

Actual Results:

Stable doesn't have this code at all, so I'll mark this FIXED.  If you can 
somehow reproduce or have further trouble, please reopen.
