file not existing warnings

[i300220]

Hi,

I've beginning to see similar error messages 2-3 months ago. Since, I see some each and every day. I updated to the latest phpthumb version but it's not fixed.

I don't understand, file existence is tested at line 585-586, but when the routine is executed, 2 warnings are issued about the file not existing and of course it doesn't exit.

L 585: if (@is_readable($phpThumb->cache_filename)) { RedirectToCachedFile(); }

Error log:

And of course, impossible to know what image or file caused this initially, I literally have hundreds of images using phpthumb.
