Is it a bug I've found?

Hi

Thanks for an excellent free software!
This is my first post ever in this forum so please be kind to me :-)

Now to my eventual "bug":

I like to have dashed voltas on my scores, but when I export my scores to PDF ,
the dashed voltas become straight lines.

Can someone else try and see if you get the same result?

I use MuseScoreNightly-2013-12-31-1507-d6d0b1a under Windows 8.1

Thanks
