Thank you for the suggestion, unfortunately I get a very similar error.
I found the id of the message I want, and when I run this function, I
get this backtrace.

  command-execute(notmuch-show-single-message record)

This seems to be the same problem as when hitting RET on a tree-view
buffer. Some huge forest is built, instead of showing the single
message. (Or maybe the forest is built before deciding to show only the
message, but there is a stack overflow before that.)

Best,
