Using the Ubuntu fridge calendar: webcal://fridge.ubuntu.com/event/ical

When unchecking the calendar box from the calendar UI, that message is displayed on the command line:
"calendar-gui-CRITICAL **: e_week_view_event_item_draw: assertion `wveitem->event_num < week_view->events->len' failed"

backtrace from "evolution --g-fatal-warnings" with GNOME 2.16.0:

Comment 1 Karsten Bräckelmann 2006-09-13 20:52:04 UTC

Unique.  Good stacktrace, of course. ;)  Thanks, Sebastien.

Comment 2 Karsten Bräckelmann 2006-09-13 20:53:27 UTC

Sebastien, if this critical warning is special to the above mentioned webcal only, please attach a snapshot of the Calendar that triggers this. Thanks.

Comment 3 Sebastien Bacher 2006-09-13 21:19:37 UTC

No, it's doing the same with www.gnome.org/start/unstable/schedule.ics by example

for evolution;

it's always better to remove item after we are finished with it, not before :)
This can possibly solve bug #352759 too, maybe.

Comment 6 Chenthill P 2007-08-23 09:11:53 UTC

The patch looks good to commit. Please commit it.

Comment 9 Milan Crha 2007-08-29 13:25:32 UTC

I didn't get all the backgroud here, this bug can still happen.
Consider a week view with only 3 event, one on Monday, one on Tuesday and one on Wednesday. They have their event_num 0-2 in this order. When you will delete event on Tuesday, then the massage appear on the console, the span->background_number->event_num wasn't updated for the last event.
