Thanks for a bug report. This seems to be related to the upstream bug [1]. Are those calendars accessed by CalDAV or WebCal?

Oh, I'm wrong, it cannot be the upstream bug, the relevant code is there, in evolution-data-server-2.28.3-10 package.

Hi Milan,

I have have some caldav calendars configured, and some webcal calendars configured.  I will attempt to make them all caldav and see if this affects evolution's stability.

Hi Milan,

Evolution had been crashing on a daily, or more frequent basis.  At the time I had 2 caldav calendars and 3 Webcal calendars.  I converted all my webcal calendar references to caldav calendars (OK, I disabled the webcal entries and added caldav entries).  Evolution hasn't crashed in the past week!

So, the problem likely involves webcal calendars.

As an experiment, I switched all my calendars to Web calendars.  I will see if this affects Evolution stability.  I am trying to differentiate between problems with Web Calendars, and problems when using both Web Calendars and CalDav calendars (for different calendars).

By the way, when I had both types of calendars, I found that Evolution crashed shortly after it received quite a bit of traffic from the calendar server - even if Evolution had been running for a long time.  Unfortunately the contents traffic is encrypted, so Wireshark won't decode it.

Now that I am using only Webcal calendars, I am getting frequent evolution or evolution-data-server crashes.  Looks like Caldav works just fine for me.

I found that evolution crashes when I have a meeting scheduled at that time in a webcal calendar.

I did a little progress on a similar issue in an upstream bug [1], which is not fixing the issue completely, but it avoids unnecessary updates of already opened web calendars. We may be able to reuse patch from there, together with a fix from bug [2].

Development Management has reviewed and declined this request.  You may appeal
this decision by reopening this request.

*** Bug 663776 has been marked as a duplicate of this bug. ***

I'm on this, thus reopening and moving to evolution-data-server.

eds patch

for evolution-data-server;

Fixes the above issue, and incorporates changes from the upstream bugs, so the calendar view is not flashing so much when updating content of a webcal in the data server.

I built a package which has the patch for this included. Please try with evolution-data-server-2.28.3-13.el6. Thanks in advance.
