The file is damaged and could not be repaired.

Intermittently when we open a pdf in the browser in one of our main Enterprise applications, we get the error "The file is damaged and could not be repaired."

Downloading and opening always works (however for our system this is a less than acceptable workaround).

The only common denominator we can find is that this is only happening in IE6 (no matter what version of adobe reader). IE7 always opens the pdfs fine, regardless of the reader version.

I've seen this mentioned all of the place, and it often mentions that it's some sort of problem with the pdf and that reader 8 handles it better.

Any solutions yet?
