[R] R crashes with "Error in UseMethod("depth")" when resizing ggplot windows

[Eike Petersen]

Hello everyone,

Quite frequently I encounter crashes when resizing ggplot windows. The
error message is always as follows:

> Error in UseMethod("depth") :
>  no applicable method for 'depth' applied to an object of class "NULL"
>
> Process R exited abnormally with code 255 at Tue Feb 24 21:51:18 2015

The error seems to occur rather unpredictably when I do several
resizings, e.g. moving a plot window from one monitor to another using
Windows+Arrow Key several times. It only seems to happen when plotting
rather large data frames.

I was about to file this as a ggplot2 issue, but then I realized that I
can't reproduce it using RStudio - normally, I use emacs/ESS (on Windows
7). So maybe this is a bug related to the "plot engine"...? The problem
is that I can't even do a traceback(), since R is crashed.

How should I proceed? Are there any other options to retrieve valuable
debug information?

Kind regards,
Eike
