Error uploading file to DAV

Drupal 6.9 hosted on MAMP.

I can connect to DAV from different clients on network, read directories and files, and create new directories which then show up in taxonomy. However, when I try to upload a file through webdav I receive the following error in Drupal falsely stating that the file was empty:

Type file
Date Wednesday, February 11, 2009 - 12:31
User XXX
Location http://localhost/drupal69/dav/WebDAV/Testing/test.txt
Referrer
Message The file converted from uri=, name=test.txt to application/octet-stream was not saved because it was empty.
Severity error
Hostname ::1
Operations

If this is a user error due to not being able to take a specific file format or the like, users should receive a more meaningful error message instead of this.

I received the following error in Mac's Finder when the upload failed:
"You cannot copy some of these items to the destination because their names are too long or contain invalid characters for the destination. Do you want to skip copying these items and continue copying the other items?

Here is the trace logging during the time of the upload:
