I've installed Apache OpenOffice 4.1.1 from the package repository, but it crashes a lot of the time when I try to save a file, and when the document recovery wizard comes up, it crashes again.

Deleting my .openoffice directory does not help. And if I remember right, this same issue plagued me with older versions of AOO on another computer with a different installation of FreeBSD.

All of these times it crashes with "Due to an unexpected error"[...] and when it crashes during document recovery wizard, it deposits a core-file in my home directory. 

Below is a backtrace retrieved from GDB using `thread apply bt all' (this provides a trace of all threads):
