[molpro-user] Triplet state calculations

Update: this error also occurs on a *serial* version of Molpro which we've
been running for a while. Similarly, it seg faults after trying to access
the 2100.2 record. There is an extra line at the end of the Molpro output
- "GLOBAL ERROR fehler on processor 0."
