Steps to reproduce the bug

1. Open the following PDF minimal-vcard-adr-test.pdf
2. Scan the QR-Code on your Android mobile device
3. Open in Contacts
4. Contact Crashes, Address is not imported

The QR-Code contains a VCard, generated from LaTeX as follows:

[1] (./minimal-vcard-adr-test.aux
<Reading QR code for "BEGIN:VCARD^^M
VERSION:4.0^^M
N:Test;Test;;;^^M
FN:Test Test^^M
ADR:;;Technoparkstrasse 2 8406 Winterthur ZH Switzerland;;;;^^M
END:VCARD^^M
" at level 11-H from aux file.>
) )

Result: If the ADR field is absent, the contact is imported, as soon as there is an ADR field, Contacts crashes. Regardless what other fields are defined and regardless on what is in the ADR field.

The visiting card is generated with xeLaTeX usig my template: businesscard-qrcode

\documentclass{businesscard-qrcode}

\begin{document}
\givennames{Test}
\familynames{Test}
\type{work}
\street{Technoparkstrasse\ 2}
\city{Winterthur}
\region{ZH}
\zip{8406}
\country{Switzerland}

\drawcard
\end{document}
\drawcard
\end{document}

Expected behavior

VCard from QR-Code is imported in Contacts.

Actual behavior

Contacts crashes when there is an ADR line.

Sometimes I get a crash report dialog, but most often it just does not open and switches back to the QR scanner.
