Ok, I did not have an rc3+GAP 4.4.12 any more since I used that tree
to test the GAP downgrade before pulling it into 3.4.1.rc4. But
3.4.1.rc2 + GAP 4.4.12: *boom*
4.4.1.rc3 + GAP 4.4.10: it works
Note that the downgrade also changed some code that was merged due to
the updated GAP, i.e. some randgen framework work to set the random
seed for more GAP functions. I kind of doubt this has a side effect
here, so now I am quite confident to blame GAP for this :)
