Bug document

Simply opening the attached presentation without any action in the GUI
or otherwise, just letting LibreOffice sit idle, spams the console with
~1500 instances of

   warn:legacy.osl:20384:20384:vcl/source/outdev/bitmap.cxx:463: 
   CopyBits with zero or negative width or height

per *minute*.

How to reproduce:

   1. Save attachment as circle.pptx
   2. Open a (Unix-type) shell
   3. date ; lo circle.pptx 2>&1 | grep CopyBits | wc -l ; date

In a test I did on my notebook, this gave me

   ... 21:06:16 CEST
   514
   ... 21:06:37 CEST


There's two issues here: the spamming of the console, but maybe more
importantly - what is LibreOffice doing in a tight loop apparently when
there is no user action at all?

On pc Debian x86-64 with master sources updated today, I could reproduce this.
