tiff(), jpeg(), and png() in R 2.7.0: problems if 'units = "in"' but default height and width

Clearly you don't have cairo installed or functional, since the preferred 
versions of these devices do not use X11, and do trap this error.
tiff("a.tiff", units = "in", res = 1200)
Error in tiff("a.tiff", units = "in", res = 1200) :
   unable to start device 'tiff'
In addition: Warning message:
In tiff("a.tiff", units = "in", res = 1200) : cairo error 'out of memory'

There is nothing new here (Xlib-based devices would crash with 
insufficient memory 'for ever'), but we will see if we can trap this.

I love the new tiff(), jpeg(), and png() in R 2.7.0 but found
an issue that I didn't see reported.

When specifying 'units = "in"' but forgetting to change the
default height and width (so the figure is unintentionally
going to be 480 inches by 480 inches) I run into problems.

Here's the reproducible example:

tiff("a.tiff", units = "in", res = 1200,
    compression = "lzw")
hist(rnorm(10))
dev.off()

Before dev.off(), I get these warnings:

Warning messages:
1: In title(main = main, sub = sub, xlab = xlab, ylab = ylab,
 ... :
 X11 protocol error: BadAlloc (insufficient resources for
operation)
2: In title(main = main, sub = sub, xlab = xlab, ylab = ylab,
... :
 X11 protocol error: BadDrawable (invalid Pixmap or Window
parameter)

and the dev.off() line will give me:

*** caught segfault ***
address 48, cause 'memory not mapped'

Traceback:
1: dev.off()

Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
