--- Comment #28 from d...@newtech.fi --- Possible explanation to why removing the line feeds in the continuation line makes things work: The line becomes too long and the email address at the end cut off due to this. Then korganizer has no idea about the identity of the ATTENDEE and can make no assumptions -- You are receiving this mail because: You are the assignee for the bug.
