Which version of Google Chrome please?

System diagnostic data from Chrome settings -> Advanced??
esp. mem_usage e.g.:-
Browser 62 MB private, 117 MB shared
Tab (Chrome) [About] 32 MB private, 78 MB shared
Extension [Feedback|Feedback] 20 MB private, 62 MB shared
Tab [Chrome] 19 MB private, 70 MB shared
Tab (Chrome) [Chrome] 15 MB private, 48 MB shared
Extension [GaiaAuthExtension] 13 MB private, 42 MB shared
Tab (Chrome) [Untitled] 7 MB private, 38 MB shared
Pepper Plugin Broker [Shockwave Flash] 5 MB private, 29 MB shared
Zygote 4 MB private, 5 MB shared

Have you tried isolating the problem by seeing if you can recreate the
issue without GIMP running? Try loading a few tabs with javascript and
flash in them (note the tabs and reuse for other tests).

Can you dump the output of top with Chrome running when the problem is
not occurring, while a minimal number of other programs are running.
Repeat the process when your system locks (you may need to ssh in from
another box).

Kind regards
