Display bug, instead of textfields random links, only in pulse and only export csv, with ms sql database

Pulse views are bugged. and csv download.

When my database uses datatype VARCHAR MAX and NVARCHAR MAX leads to this bug

The ms sql database uses the following encoding:

i am on metabase version 0.25.1 in firefox, onclick deployed on heroku
in the picture the text for the sample database gets displayed nicely

the dateandsource field should display something like: 2017-07-29-fromxy
the second pictures i show for the demo database it works fine for me
