Steps to reproduce the bug

• Go to Setting
• Select Import contact from .vcf file
• Select vCard v4.0 file stored on Smartphone. Click ok to import. Import starts.
• Two seconds inside the import process (that time is fully reproducible), a message pops up on smartphone display.
• Message content: "JavaLang: NullPointer Exception: getPartialDate()..." Followed by "Importing some items failed." (translated from German).

Expected behavior

More than 4000 vCard should be imported, instead of 372.

Actual behavior

• After error message appears upon importing vCard file contents, go to application main screen: observe that only 372 contacts were imported out of more than 4000.
• Replicated 8 times.
• The exact same 372 cards are imported everytime.
• Among those 372, 5 contain Chinese characters and a lot more contains diacriticals such as é, è, ï, à, ñ, ç, etc...
• All imported card are correctly imported (their content is complete and not mangled.)

Additional information

• The adjoined file with which you can reproduce the malfunction was anonymized. For some reason it only permits imports of 367 vCards, not the 372 previously observed for a non anonymized vCard file. However the error message remains the same. The file suffix "txt" was added only because "*.vcf" files cannot be attached here.
