I had a go trying to duplicate this but sadly failed.  Can you maybe
re-compile with debugging symbols and try to get a stack dump of the
crash? i.e. do:

make clean
CFLAGS=-g  ./configure --prefix=/opt/redland-0.9.19 --with-mysql=/opt/mysql-3.23.58/bin/mysql_config --with-bdb=/opt/db-4.1.25
make
sudo make install
cd utils
gdb --args /opt/redland-0.9.19/bin/rdfproc -s mysql -t "host='server',database='redland',user='seebi',password='xxx'" -n archive parse http://sebastian.dietzold.de/rdf/foaf.rdf
...

gdb> run

and then when/if it crashes, do 'bt'

(you might need to set some source directory paths for gdb:
 gdb> dir /absolute/path/to/redland-0.9.19/librdf
)

Thanks
