We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

Looking for the cause I found that gpg --export creates an utf-16 LE 
file and gpg --import expects ascii or utf-8 without bom but not utf-16 LE

The same test file imports good in Kleopatra.
