Attached pls find another valgrind log.

This time around -store didn't get stuck like it did previously. I had
to use TERM (15) since HUP (1) failed. Here's the last messages
(G_DEBUG=gc-friendly G_SLICE=always-malloc valgrind
--track-origins=yes --leak-check=full --show-reachable=yes
--leak-resolution=high -v --log-file=valgrind-TS.log

the summary looks strange, especially since valgrind was eating 1.1GB of RAM
