Calibre Companion PDF Corruption

Hi,

Generally, I've had lots of success with Calibre Companion, but I have a few (not all) PDFs which get corrupted in the "Send to device" process.

When I open the content server in Calibre, I can download the files into (e.g.) MoonReader and open it just fine, but when I send the PDFs to Calibre Companion wirelessly, the resulting file in unreadable in MoonReader, Adobe's PDF Reader, and a few other apps. They all describe the file as "damanged or corrupted".

I compared the file in Calibre_Companion on the device with the file in my local Calibre library (using WiFi File Browser to transfer it), and they are different sizes, and have different content (see below):

cksum working.pdf broken.pdf
2897500834 619196 working.pdf
4245409161 616740 broken.pdf

Just to really mix things up, both PDFs are openable, and appear to work fine on my mac laptop - it's only on the mobile device that

So my question is how can I get the PDF file to be transferred without any processing.

Thanks in advance for any advice,

Andrew

P.S. For what it's worth:

Calibre 0.9.16 on OS X 10.8.2
Calibre Companion 2.7.1 on Android 4.0.4 (Galaxy Tab 10.1 GT-P7510)
