After loading qtbase, closing quartz windows crashes R

library(qtbase)
plot(x)
# Close the plot window

#  *** caught segfault ***
# address 0x18, cause 'memory not mapped'

Simon may have to be involved with this one. It looks like the qtbase event loop is driving the Quartz event loop, which tries to release memory at the wrong time. There is a related issue btw with Windows where Qt (or something) aborts when R is closed, which is likely related to the killing of the Windows event loop.
