Yes - it is 100% reproducible.

I've found out that the crash only happens with the kernel 5.8-rc. 
Aptitude works on 5.7. So, it may be bug in the kernel and not aptitude. I 
bisected it, and it is caused by the kernel commit 
d27865279f12035c730818aa1a0280fada866a37.

I am running debian unstable in a virtual machine on the MacchiatoBIN 
board.
