Hi Marcelo;

Can you tell us what versions of notmuch, gmime, and xapian you are
running?

Maybe you can try to get a backtrace? 

1) make sure you have the debugging symbols. If you compiled from source
this should be fine, otherwise if possible install the debugging symbols
package for your distro (on Debian and derivatives this is called
"notmuch-dbg")

2) run "gdb /usr/bin/notmuch" or equivalent

3) type "run new<RETURN>"

4) when it halts, type "bt full".
