evolution crashed with SIGSEGV in g_signal_emit_valist()

Binary package hint: evolution

Reproducible crash when switching to Calendar view. Looks like a release blocker, didn't happen two weeks ago.

thank you for your bug report, the crash is similar to http://bugzilla.gnome.org/show_bug.cgi?id=551845

[Allan Caeg (allancaeg)]

I know it's odd but it works fine on KDE4 Intrepid. LOL

[gadLinux (gad-aguilardelgado)]

The information reported by Timothy Alexander in bug #290796 works:

----
FYI for future people.

To disable accessibility, got to System->Preferences->Assistive
Technologies

Uncheck the "enable assistive technologies" box.

I get this bug too when I run
$ evolution --component=mail
but not when I run evolution without any arguments.

[Michael (m-gruys)]

The bug does not occur anymore when you login with ssh -X <host> with another (virtual) machine and start evolution in the shell!
Then evolution does not crash anymore :-)
Strange....

[Michael (m-gruys)]

Please ignore my last comment.
It is as 'gadLinux' wrote: Uncheck the "enable assistive technologies" box. (System->Preferences->Assistive
Technologies)

But this was not enough for me because some processes which use this Technology were in use.
I had to log out (come into greeter screen) and do a <CTRL><ALT><F1> en log in as root
then I had to do a pkill -u <username> to kill some remaining locked processes
And then indeed the bug does not occur anymore

[Benjamin Couhe (voraistos-googlemail)]

I don't have assistive technologies enabled, I have tried launching evolution with and without options, and the bug only occurs when, in the calendar section, i try to click on the default "contacts" section in the tree.

Last night Evolution was working fine, this morning, without having changed anything, it crashes with a sefault if I try to use the button at the bottom of the sidebar to switch to the calendar. (Ubuntu 8.10 AMD64, Evolution 2.24.1).
Experimentation has shown me that I can invoke the program to open directly into the calendar by double clicking on a date in the drop down from the clock applet. Then it will behave as normal, during that session.
If I then shut the program down in any view other than the calendar, it will segfault when I try to click from any other view, mail, memos, etc, to Calendar.
If I shutdown with in the calendar view, the program runs fine next time.
There is no record of the event in /var/crash, and I am not tech enough to know how to trace what's going on.
Using a terminal to start Evolution doesn't tell me much, as per the attachment.
At least I have a workaround, so it's only a minor annoyance.
Regards,
Bruce

Shortly after posting the above, and closing down the computer, I found, on rebooting that I had the famous ".dmrc file being ignored" pop-up.
Attempting to fix that via the terminal, I must have entered a typo when recursively changing the mode and ownership of my home partition, and lost /home, and of course, booting, for a couple of hours.
After repairing that problem (via google and my WinDoze part: good thing the machine is still dual-boot!) Evolution is behaving normally. Go figure.
Kind regards,
Bruce.

[Sebastien Bacher (seb128)]

the bug has been fixed upstream now

[rrichter (rrichterzittau-deactivatedaccount)]

Cant found a bugfix with apt-get update !
The program crashes again.

[Sebastien Bacher (seb128)]

upstream rolled a new stable version today which has been uploaded as a candidate update to intrepid now

[Sebastien Bacher (seb128)]

the new version is in jaunty now

[Apteryx (maxco)]

Happened to me in the latest Karmic. Apport was used to submit report. Bug is not really reproducible though. If I nail how to reproduce it I will post here.

[m0m0 (a0005783)]

I must confirm what Apteryx said (on Karmic Beta AMD 64). Can't reproduce it either and was the first time since I use the beta.

[Pedro Villavicencio (pedro)]

Please open a new report with apport rather than re opening this one which was closed several months ago, thanks.
