Not sure why, but in sugar-jhbuild, where I do most of my work, it
seems to reindex fairly often (~1 out of every 30-40 sessions
launched). one trigger *seems to be* changing the display size, e.g.,
if I use 1200x900 sessions for a while and then switch to 800x600, it
will often reindex. (Likely nothing causal there.)
