           Summary: FILEOPEN hybrid PDF not recognised when opened from
                    CIFS share
           Product: LibreOffice
           Version: 6.1.3.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium

          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: lionel at mamane.lu

Description:
A hybrid PDF containing an OpenDocument Text or Spreadsheet embedded opens as a
regular PDF (in Draw) when opened from a CIFS share mounted from a Microsoft
Windows Server on a GNU/Linux machine.
The exact same file, byte for byte, opens correctly in Writer or Calc,
respectively, when opened from a local filesystem (ext4).

Steps to Reproduce:
1. Open hybrid PDF


Actual Results:
Opens in Draw as a normal PDF

Expected Results:
Opens in the LibreOffice component appropriate for the kind of OpenDocument
embedded in the PDF.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Debian GNU/Linux
kernel 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
CIFS mount options:
rw,relatime,vers=2.1,sec=ntlmssp,cache=strict,username=USERNAME,domain=DOMAIN,uid=UID,forceuid,gid=GID,forcegid,addr=IPV4ADDRESS,file_mode=0600,dir_mode=0700,nounix,serverino,mapposix,rsize=1048576,wsize=1048576,echo_interval=60,actimeo=1,user=USERNAME

Version: 6.1.3.2
Build ID: 1:6.1.3-1
CPU threads: 8; OS: Linux 4.9; UI render: default; VCL: gtk3; 

Dunno if OpenGL is enabled, there is no such checkbox in
tools/options/libreoffice/view. The "use hardware rendering" checkbox is
checked. Probably not relevant to current bug, but the bug report wizard
asks...
