Multiple newlines in textbox give invalid latex on pdf/latex export

[Frederik TIlmann]

When exporting to pdf/latex and there is a text box with a double newline (i.e. an empty line), then the resulting latex file does not compile.

Example textbox content
"some text

some more text"

The reason is that each newline generates a "\\" command, and in the minipage context a repeated newline " some text \\ \\ some more text"

Instead of "\\ \\" the double newline should be converted to
"\\[\baselinskip] " or
"\\ \hspace*{0cm} \\"
which both give the desired empty line.

As the workaround is easy, not a big deal, but should also be fairly easy to fix.
