Confirming, since there's a duplicate. Seems like there is no sensitive information either, so setting the bug to public visibility.

[Mathieu Trudel-Lapierre (cyphermox)]

Jono,

Do you remember if the calendar you were adding was a public calendar in case we could try to reproduce the crash?

The stack trace indicates an issue in converting the time zone for a recurring event, but I couldn't really reproduce the crash or make sense of why this would cause a crash in libical the way it does.

[Brendan_P (brendan-p)]

Just experienced this in 12.04.

I have multiple time zones (SAST/GMT) in a google calendar that's pulled into evolution.

[Brad Heap (nzv8fan)]

Same problem here as Brendan_P, as part of Gnome 3 the calendar appears off the top bar when you access the calendar, when it downloads from Google I have events in multiple time zones and hence the crash.

[Lars Falk-Petersen (julenissen)]

This happened for me when enabling a private calendar (birthdays & anniversaries), that was set up by 11.10 as part of automatic google setup.

[Brendan_P (brendan-p)]

I'm no longer seeing this issue having previously been affected by it.
