Table of error/succes on export modes
(Some?) vector image filter can not export empty documents, but the error
message is too general. Because similar export actions to other formats do
work, this looks like an error in the export filter.
This may be by design or for technical reasons, but from the user side this is
not obvious.
I did a batch of testing before I noticed it seemed to be only vector shapes
that gave this error.
How to reproduce:
Start LO draw document, do not save. Export>choose file format>export.
Add shape to the document: do not save. Export>choose file format>export.
(repeat actions after saving)
Export to Windows empty Windows content Linux empty linux
Content Linux saved empty windows saved empty
PDF success N/A
GIF fail (empty) success (with content) fail success
fail fail
BMP success success success
PNG fail (empty) success (with content) Fail, success
fail Fail
WMF success success success
SVG success success+fail success success
As stated in related earlier bug report, the error message should be updated

<span class="quote">> still a more helpful error message would be more helpful</span >
Please file a separate issue about a better error message in case of wrong user
input, which is a different problem. Thanks!"
Suggested improvement for error message:
"warning, you are trying to export an empty document. Vector shapes do not
support this"
+ add to documentation</pre>
