evolution 2.32.2-0ubuntu7 suddenly kills calendar, tasks, memo

[rick beldin]

When using evolution to manage calendars, the calendar will suddenly create popups that say "The Evolution tasks have quit unexpectedly. Your tasks will not be available until Evolution is restarted. " A total of 3 popups are created, one for calendar, one for tasks and one for memo. This is somewhat random but appears after moving the calendar through several entries and hovering to display the entries. It takes no more than 2 minutes to make the problem appear. Mail keeps functioning.

Similar problem was reported with 10.04:

https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/838963

The difference now is that the notification area does not immediately cause the problem.

Email is configured to use IMAP. Many calendar entries are repeating.

This laptop was upgraded from Lucid.

Sample run after shutting down evolution. I created on new calendar event, viewed another, and then clicked on the Mail button. Within 5 seconds the popups appear. Never connected to imap server.

Observations during testing:

- As far as I can tell, this is some sort of handled condition within /usr/lib/evolution/e-calendar-factory and evolution. No sigsegv's.

- /usr/lib/evolution/e-calendar-factory does not exit

- killing it while keeping evolution started does not cause it to 'reconnect' to evolution

- this thread shows 'similar' problems without the segv

Downloading source, cscope shows only a few hits in the 'e-*' part of the code which I 'assume' means the e-calendar-thingie and none of the others are assertions:

Functions calling this function: g_utf8_validate

  File Function Line
0 e-name-western.c e_name_western_parse 941 if (!g_utf8_validate
                                                     (full_name, -1, (const
                                                     gchar **)&end)) {

  this seems to be from here:
