Calendar invitation e-mail address garbled

When creating iOS Calendar invitation e-mail address is garbled by iOS. Have anyone seen the same? This is different than other reported bugs in this forum with topic Calendar invitations not sent.

This is how I did invitation.

1. Create invitation

2. Invite by entering e-mail, NOT contact, example: my.name@adr.com

3. iOS will notify that mynameadrcom is not a valid e-mail address, i.e., e-mail address with ALL dots and @ removed! 😕 See picture below, with parts of address hidden.

I have the same bug in ML 10.8.2. However, no warning, no logs, "only" effect is that invitation is NOT sent.

Best regards,

Claes
