Evolution segfaults when opening mail with ICS/VCALENDAR attachment

[Dennis L.]

Upon opening a mail that has a ICS/VCALENDAR attachment Evolution will hang displaying "Retrieving message xxxxxxx-xxxxxx" for a few seconds and then segfault.
This has happened with ICS/VCALENDAR files from various sources.
After digging the web I had found one case where german "umlauts" (maybe non-ascii characters) would cause the crash.
As my last name contains such a character I have prepared an ICS file and removed all possible offending characters and made a new test which resulted in the same crash as before.
I have attached the (anonymized) offending ICS file used for reproducing the bug.

As of Ubuntu 17.04 opening emails with ICS/VCALENDAR attachments in Evolution appears to work just fine.
Apparently this problem is solved.
