Maybe xtc-grps was set to "protein"? That wouldn't be related to the
problem. But did the crash occur directly, at step -1/0/1, or did the
system run at least for a few steps? What exactly were you doing?
Please copy-paste your command lines, your .mdp file and the mdrun
output (not the log file yet, please).

Cheers,

Tsjerk
