Line breaks in "Activity Description" break CSV import

[martin-ueding]

I also get an import error with 0.26.2.
the activities.csv from the zip file shows 94 columns.

In the cases, where the "Activity Description" contains a line break, there is a very strange break in the csv as well and the entry spans over two or more lines, not aligning with the "traditional csv structure"....

That's nasty. Perhaps I'll need to write my own CSV parser to catch these issues. I'll think about a way to fix this.
