I'm receive "Error: header not recognized" and "cpio: premature end of 
archive" when attempting to process the following using rpm2cpio:

https://download.vivaldi.com/stable/vivaldi-stable-1.0.435.42-1.x86_64.rpm

I commonly use rpm2cpio to process rpm files and have had the issue with 
all Vivaldi's betas.  I see nothing about such a problem on their site 
so assume it's unique to rpm2cpio.  I don't use a distribution with an 
rpm extractor.

Can others successfully process the file?
