Note Import Failure: Big PDF Attachment

[fxcormontagne]

I tried to import one notebook containing 287 notes. Each note contains one PDF file - an archive of my newspaper.
One note out of 287 failed to be imported. It contains a PDF of 8MB. But that is not the biggest. Other notes have a file of 13MB for ex. and were imported successfully.
I am attaching the failing note as a zipped file.

Beyond this I can just praise your work !
