segmentation fault

segmentation fault

[Marko Bauhardt]

Hi,
I'm using notmuch since a while to index my mail.
Since a few days I'm getting a segmentation fault when search my mails.
This happened to my when tagging my mails based on a search query.
I believe this happened when I upgraded my osx before some days.

I removed already my whole index and index my mails only with 'notmuch
new' without any other tags.


I used valgrind to get a stack where or how the segmentation fault occurs. Not sure if this is a good way....
Anyway here is the output.
Maybe you can help me to find a way to fix that to get my index up and
running.

Versions about notmuch and xapian can be found in the stack below.

thx
Marko

At a guess, it's this xapian bug
