Dear pauwawa87,

Thanks for pointing us this bug. It is related to the use of ionmov = 5, which is not very common (for relaxation, we often prefer to use a Broyden algorithm).
The fix has been submitted for the next version of Abinit.
In the meantime, you can work around the problem by adding "optforces 1" in your input file
