The tarfile within the .tar.gz file available for download here (eric4-4.5.16.tar.gz) contains 'pax headers', which it seems 7-Zip does not support.

These headers appear to 7-Zip as files. You're getting an error because data from some of these pax headers is overwriting .ui files which should contain XML documents describing how parts of the GUI are built. Of course, the data in the pax headers isn't XML, so you get an XML parsing error when PyQt tries to parse these files as XML.

This problem has arisen before here and here. The latter even suggests (to me, anyway) that to generate a .tar.gz file without pax headers, you only need to remove a switch when you generate the archive.

It is inconvenient that this happens, given that 7-Zip seems to be the go-to tool for extracting .tar.gz files on Windows. Given the popularity of 7-Zip, it would seem wise for the Eric developers to remove the pax headers from this .tar.gz file, if possible, as it would prevent further confusion. I don't know if they have a reason for using these headers.

In the meantime, if you're using Windows, I'd recommend using the .zip file (eric4-4.5.16.zip) instead.
