(ITS#3945) segfault in 2.2.26

Submission from: (NULL) (

Just ran into this (unreproducible) segfault on 2.2.26. Unfortunately because it
occurred on a production system I was not able to investigate further.

However, I am seeing regular crashes in 2.2.26, which I am looking into.
Hopefully I'll find out that it's something that was fixed in .27 or .28.

Program received signal SIGSEGV, Segmentation fault.
