when clicking the cover art in the lower left corner of the song being played then iTunes shows player controls when the mouse is hovered over the artwork window. when another song is selected for artwork display it cannot activate player controls and crashes as soon as the window is resized.
Hah! I've been resizing the wrong thing. I take it back, Peter, I
can replicate your issue in its entirety (XP SP3 English localisation). Same iTunes.dll being cited by my "iTunes has encountered an error" message when I click the "Click here" link in the error message.
Level 4 and 5 members here get access to a "Notable New Technical Issues" forum (in the Lounge), so I'll write this up over there (probably later on ... it's coming up for 2.30 am in New Zealand).
At your end of things, it's possible to make bug reports via the iTunes product feedback form:

But if you want to
track a bug report, it's possible to sign up (for free) as an Apple developer:
