Any ideas on this crash?
It appears that the ASN.1 dissector registered with TCP, UDP, and SCTP port 801 even if it hadn't read in any file, and thus was called even if it had no "PDU tree", and thus cheerfully dereferenced a null pointer and crashed.
I've checked in a fix, which will be in the next release. (I don't know when that will be.) 


Is there any way I can disable ASN.1 to see if that is the cause?
You could disable the ASN.1 dissector - Analyze > Enabled Protocols, and turn off the "ASN1" ("ASN.1 decoding") protocol.
