BePDF ask for password for non-protected document

[Briseur]

When you double click on PDF document, BePDF ask for a password for documents that are not password protected.
It seems to happen in these conditions:
. Documents are located deep in directory structure (sub sub sub folder) of a foreign partition (ntfs).
. BePDF was not open before.
If BePDF was opened before hand then opening the file via the menu or double-clicking works as expected and no password is asked.
If one of these documents is copied on Befs partition, no password is asked.
Note that XpdfReader seems to have similar problems.
