Workaround found:

Patched the UID to some RFC 822 content: [e-mail]
(patched ICS file attached)

Result: Works!

Looks like this is a duplicate of bug 465853. Can you cross check this?

It's definitely not a duplicate, but it looks like both cases can be tracked down to a common root cause/bug, which is:

Events with a slash in the UID can't be processed by Lightning up to now!

The referenced bug however contains much information that (mistakenly) suggests that this was only a display issue and only related to Google calendars.

Looking at the standard, RFC 5545:
UID is of type TEXT, and in the corresponding section 3.3.11 I don't see any note that a slash wasn't allowed or must be escaped.

Comment 4

[Philipp Kewisch [:Fallen] [:📆][:🧩]]

Thanks for the report. If this has the same root cause, I think we can make due with a comment on the other bug on what is different. It was not a display issue, but Google incorrectly handling slashes and not finding the event, and us also not encoding correctly.
