What I see from the backtrace looks like:
1/ metrics are computed for some info inset
2/ the info inset is regenerated (and thus the paragraph it held is now 
invalid)
3/ We draw the inset and because of the new (disabled by default) 
bookmark display code, we access the id() of the invalid paragraph.
4/ boom

This scenario can probably be verified using valgrind.

A short-term solution would be to avoid accessing the paragraph data 
when not showing bookmarks, but this would be just a band-aid.
