This results in a properly fragmented molecule, except for a single ILE residue. 3 atoms of this residue somehow remain displaced by the box size, while the other atoms of the same residue are correctly placed onto the protein. Is this a bug? If so, is there any way to circumvent it? (I use 5.1.2)

Without an exact sequence of commands, it's impossible to tell what may have 
happened.  It is extremely doubtful that trjconv has a bug in simple PBC routines.

Reconstructing "broken" molecules should be trivial with trjconv -pbc mol and a 
.tpr file passed to -s.
