Ever heard of mixed-up files?

Hi all,

Ive just stumbled over a really interesting issue;
A customer called me and asked why PDF-files on their site gets mixed up.

For example:
The customer uploads a pdf to the site. Lets call it filenr1.pdf.
Initially everything works out great. But...

Later on, when a visitor on the website visits the page, and clicks on the file for download, some really interesting stuff happens.

While the file still is called filenr1 on the webpage, and in the download dialogue window, it is another file that opens in Acrobat reader!

Thus, it seems like the system changes the content of the file at some moment. The file retains its original file name, but the content seems to get mixed up.

Has anyone of you seen this issue before? Maybee I should file it as a bug... I just want to rule out any possibility of user-induced errors before...

Appreciate any feedback on this.

Kind regards,
/Nicklas
