R devel - Apr 2007 - Error: An unusual circumstance has arisen in the nesting of readline input

Hi,

If I have warnings converted to errors, and if I plot a simple plot and 
then resize and move the plot's window many times, I eventually get an 
error "Display list redraw incomplete", and after a while an endlessly
repeating error "An unusual circumstance has arisen in the nesting of 
readline input".

I cannot stop it using Ctrl-C (Ctrl-Z works though).

I'm using R 2.5.0 inside a gnome-terminal on Ubuntu Dapper. See more 
details below.

Thanks,
Gad
