[PATCH][REVIEW 3-4] fdo#31966: do not create an empty slide when printing handouts

[Ivan Timofeev]

Hi,

https://bugs.freedesktop.org/show_bug.cgi?id=31966

This bug was fixed in 3-5, but I didn't propose it for 3-4, and that was 
confusing to the bug reporter. So, taking into account the simplicity of 
the patch, I'd like to see it in 3-4. The patch for the "impress" 
repository is attached.

Sorry if it is insignificant for that branch.

Thanks,
Ivan
