Thank you for your report!

However, processing it in order to get sufficient information for the

I encountered this bug when I tried to add a CalDAV calendar from Google Calendar. The calendar was being populated, but crashed shortly afterwards. It now keeps crashing every time I open Maya.

Same as @Stef here. I cannot use it any more

can't use it too :(

I tried to file a report on this issue with an updated system, but it was marked invalid for the same reason mentioned here in Shnatsel's comment.

The temporary workaround for the crashing issue, is to delete the CalDav file in /home/.config/evolution/sorces , but you're still unable to add caldav calendars. Only the default google calendar works (ie. the one associated with your personal email).

@zeeeee cool, now maya start. However, i cannot use Google (as soon as I
write the password, maya crashes and return in the "non working" state).

Ok, so I think I found a way to import all google calendars and a clue on the crash issue.

First of all, the default (personal) Google calendar always worked for me, in calendar type you chose "Google", then its just your username (you don't even have to put the "@gmail.com" part), and after you finish it, it will ask you for your password. Standard stuff.

Now to import any other Google calendar (shared calendars, for instance):
1 - you have to find the CalDAV ID, go here https://www.google.com/calendar/render#j , then select the calendar you want, and you'll find something like this "<email address hidden>"
2 - then in Maya, add a new calendar, select calendar type "CalDAV", and give it the name you want.
3 - in the URL write "https://www.google.com/calendar<email address hidden>/events" , and check "Use a secure connection"
4 - NOW THIS IS IMPORTANT: in the previous point, the url bar in Maya already has "http://" written, YOU HAVE TO INSERT AN "S" so its "https://, and this is the reason it crashes, I think.
5 - from here on its straight forward, your username, your email, your password, and your good to go, I hope.

You have to do this for every single calendar. Mine are working flawless.
I also hope this helps developers fix this issue.

Ok this is really strange. Adding the calendar using Google ->
<email address hidden> cause a crash. Using myname (without @gmail.com) *does*
work.

The events are shown for a short period when first adding the calendar to maya, then it just crashes with above message.

thank you Nicolò Balzarotti (anothersms) for this hint!
Now I can use maya :)
Thank you so much!!

I've try adding google calendar using only my username (without @gmail.com), but maya still crash

Mohamad Putra Maghribi, look at my comment in #11, delete everything inside folder /home/.config/evolution/sorces

Hi zeeeeee, i have deleted all files inside that folder (only one file existed there)

Mohamad Putra Maghribi, after doing that, you have to add goggle calendar following my post #13

Hi guys,
I have the same issue on elementary os freya, following zeeeee posts (#11 and #13) does not help. I'm using Frensh localization, Any ideas.

I am on gentoo with maya-calendar latest version from the repository. With 0.3.1.0 it crashed and made the whole program unusable and segfault at startup. With 0.3.1.1 import only fails without making the whole app segfault.
My locales are on en_US-utf8 but the ics was in european french/belgian format.

@nado

Even with the latest installed version 0.3.1.1+r798+pkg70~daily~ubuntu0.3.1, Maya crashes for me on launch if I use it in conjunction with a Google Calendar.

is it related or even duplicate of/to https://bugs.launchpad.net/maya/+bug/1420431 ?

I'm having the exact same problem, but just with one of my subcalendars. I'ts the only calendar I have shared to other persons, may this be a problem?
(Although calendars shared from others to me are working....)
The rest is the same between all of them...

I'm on Loki.

The #13 can't work for mi at Loki 64 bits fresh instalation, also in Freya can't use it, I upgrade the version for try solve this but the same bug appears. I tried all the steps but google denied somtimes or the app said caan't exist the direction. If I launch on terminal:
