Plugins (and any local customizations) can always cause problems like

So, that doesn't mean Logos are broken, it just means you have GD
installed without png, jpeg or gif support.  I'm not quite sure how
you've managed that.  Perhaps look for additional gd- packages you
should have installed.

So, since you keep referring to the GD Is disabled message, which is
different from "is broken" can you be specific about what kind of
"breakage" you see with charting?  I had thought you meant that the
graph doesn't show up at all, or is a broken image link, but since you
claim that RT-Authen-ExternalAuth 0.25 still breaks it, I find that
hard to believe.

This may all be tied to your lack of gd library support referenced
above.
