Good question, I had not done an installation in a while ;)

The html and ppt save/export options are still available
And they are not working anymore:

Trying to export as html crashes LibreOffice:

  /usr/libexec/ld-elf.so.2:
  /usr/local/LibreOffice/program/../basis-link/program/libsdlo.so: Undefined symbol "_ZN10HtmlExportC1EN3rtl8OUStringERKN3com3sun4star3uno8SequenceINS4_5beans13PropertyValueEEEP14SdDrawDocumentPN2sd12DrawDocShellE"

Saving a file as .ppt opens a dialog box:

  Error saving the document Presentation:
  Write Error.
  The file could not be written.
  [OK]

It was a build from scratch.

I now see that I was mistaken: even though none of the symbols from these
files are directly used in LibreOffice, the binary containing them is
loaded explicitely at run time, bypassing the normal shared library linking
mechanism.

I thought UNO was a sort of interface for external plugins but these export
functions also use it :-(
