I can reproduce. In addition to a SIGSEGV, I get the following output that
perhaps is useful:
/home/scott/lyxbuilds/master-master/repo/src/Paragraph.cpp:4283:12: runtime
error: member access within misaligned address 0x00650000006f for type 'struct
Private', which requires 8 byte alignment

This is the result of the InsetInfo mess. This inset is hackish in
various ways. In 12dfdbf0a3e6, I have tried a new strategy, we'll see
whether it works. I am reasonably confident, but not totally. Something
had to be done anyway (see commit message below).
Testing welcome.

Fix crash in InsetInfo when bindings change
This is actually a generic InsetInfo issue:
1/ the contents of the inset is computed in updateBuffer, so that it
is available for drawing but also for latex output (think batch
export). When it is called, it deletes the existing inner paragraph
and replaces it by a new one
2/ metrics build a new Row object that represents to paragraph
3/ draw() relies on this information
Now, imagine that updateBuffer() is called after metrics(). This can
happen for many reasons, and does happen here (display a shortcut info
and change the shortcut file from cua to emacs).
This problem has been here forever, but is only visible now that the
(experimental) bookmark display code needs to read the underlying
paragraph id.
The solution is to compute the inset contents at metrics time. This
is done by moving the relevant code to a new standalone build() method
that is called in metrics() but also in latex().
