Description sourcemaker 2021-04-25 12:46:37 UTC

iCalendar files with attachments are read incorrectly and therefore the file name is not displayed in the calendar. 

Current implementation:
ATTACH;VALUE=BINARY;FMTTYPE=application/zip;ENCODING=BASE64;X-LABEL=filename.zip:

Expected implementation:
ATTACH;VALUE=BINARY;FMTTYPE=application/zip;ENCODING=BASE64;FILENAME=filename.zip:

Kontact/Calendar uses the property X-LABEL instead of FILENAME.

Is that on purpose?

Indeed, FILENAME is a Caldav standard by now.

I'll see what I can do.

icalformat_p.cpp - support ATTACH parameter FILENAME

FILENAME is allowed per RFC860
Calendaring Extensions to WebDAV (CalDAV): Managed Attachments

Note that KOrganizer still writes back the Incidence
attachment's label with the X-LABEL parameter.
