I unpacked the contents of the zip file that you sent us into my
/home/enno/.gramps/gramps34/plugins folder and received an error message
about not finding SourceOption for import. When I put a # on that line
to comment that part out, the report ran fine. I haven't tested this on
Windows yet though, only on Xunbuntu 12.10, with the latest gramps34,
which is 3.4.3-0.SVN20854.
First impression is that it looks good, some German terms need to be
replaced by gettext calls, like Fundstelle and leer, and that I would
like to see things sorted on source title. I like it!
