Description Ray 2022-09-13 18:58:37 UTC 
Description:
can't open a particular pps file in libreoffice.... says incompatible version
(had to convert it using an online conversion site to a pdf and then look at
it as a pdf)

Error says
"Version incompatibility"
"Incorrect File version"


Steps to Reproduce:
1.try to  open the given particular (old version???)  pps file
2.since you have no place to "attach" the particular pps don't know how you can 
attempt to "reproduce" the error


Actual Results:
error message as above
Error says
"Version incompatibility"
"Incorrect File version"

Expected Results:
that it would have opened the file


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
 tried updating LibreOffice .... same results with this
particular file
all i can do is convert it to a pdf to see the contents
also when added extension .zip to file i could open
it in 7-zip and see files (not photo contents or version info)

I tried to open the file and had the same result as you did.

I also tried to open it in OnlyOffice and it did not open as well... but I got a message saying that the file is password protected.

On pc Debian x86-64 with master sources updated today, I could reproduce this.
Here's part of the code which fails:

1448         ReadDffRecordHeader( rStCtrl, aDocAtomHd );
1449         if ( aDocHd.nRecType == PPT_PST_Document && aDocAtomHd.nRecType == PPT_PST_DocumentAtom )
1450         {
1451             aDocAtomHd.SeekToBegOfRecord( rStCtrl );
1452             ReadPptDocumentAtom( rStCtrl, aDocAtom );
1453         }
1454         else
1455             m_bOk = false;

(see https://opengrok.libreoffice.org/xref/core/filter/source/msfilter/svdfppt.cxx?r=8611f6e2#1448)

(gdb) p  aDocHd.nRecType
$9 = 45597

(gdb) p aDocAtomHd.nRecType
$10 = 22945
