my debut-log is full ONLY of "Aq_Resize.process() error"... Why???

[cecofuli]

Hello,

I think that nobody will answer me, but.. I will try... ^__^
I'm very newbie so, sorry if my question will sound stupid.
I bought a Calafate theme. It's a great theme.
But, I've discovered that my debug.log file is huge because it's full of this error:

Aq_Resize.process() error: Unable to resize image because image_resize_dimensions() failed

The Calafate guy told me that it's not a big problem but.. I want to understand why I have this message.
Can you help me?
thank you.

Francesco
