Description Christoph Paasch 2008-12-16 11:56:51 UTC

Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    Ubuntu Packages

Hi,

when I'm in the Summary View, and use the keyboard shortcut to switch to the calendar view, Kontact crashes.

When being on the Mail view, no crash happens.
Here are the debugging symbols:

Application: Kontact (kontact), signal SIGSEGV

Comment 1 Christoph Paasch 2008-12-16 12:05:03 UTC

I experienced, that when I set my Kontact-shortcuts to default, everything is working fine. (however I didn't changed the shortcut to switch to the calendar view to reproduce the previous bug)

Maybe this might be due to the switch from kde3 to kde4 ???

Another issue is that when I set my own shortcuts to switch the view, they don't work...

Seems to be a bizare bug...

Comment 2 Christophe Marin 2008-12-16 12:15:52 UTC

> use the keyboard shortcut to switch to the calendar view, Kontact crashes.

Which shortcut exactly ? Ctrl-4 ?

I'm able to make Kontact crash but not with this shortcut (and with a different backtrace, I don't think this one is related).

If you're able to reproduce the crash, can you please install the debug packages for kdepim and kdepimlibs and paste a better backtrace ?

Comment 3 Thomas McGuire 2008-12-16 12:28:42 UTC

This looks a bit like bug 174065, but that one is happening in KMail, and only in the new KDE 4.2 version. However, the qt-copy patch might help here as well.

Backtrace of the bug

Comment 5 Christoph Paasch 2008-12-16 12:48:22 UTC

OK,

I reproduce the bug, doing this:

Start Kontact
Settings -> Configure Shortcuts -> Defaults -> OK
Click on Summary View
Ctrl-Shift-6 to switch to the calendar view (i need the Shift to use the numbers on a belgian/french keyboard)

Then it crashes

By the way, all the other shortcuts are working properly.
If I want, that it doesn't crashes, I first have to switch to one of the two views just beside the calendar view (Ctrl-Shift-7 or 5) and always going back to the summary view (clicking, or using Ctrl-Shift-9)

In kontact, I use the modules KMail, Kaddressbook, Korganizer, Akregator, Kjots and the Popup Notes

Comment 6 Christoph Paasch 2008-12-26 09:50:58 UTC

Any news about this?

I still have the problem in KDE4.2 beta 2 (from the ubuntu packages)

Comment 7 Christophe Marin 2008-12-26 13:28:38 UTC

> Any news about this?

I'm unable to reproduce this crash.

As mentioned by Thomas, your backtrace looks familiar and may be caused by a bug in Qt4.

We have a patch is the version used for KDE development but it's up to your distro to add it to your Qt packages.

Also, what is the modules order in your Kontact sidebar ? from top to bottom it should be : Summary / Mail / Contacts / Calendar / To-do List / Feeds / (others)

The calendar view shouldn't be mapped to ctrl-6 but ctrl-4

Comment 8 Thomas McGuire 2009-01-03 14:17:02 UTC

I can now always reproduce this by switching from summary to calendar using the sidebar.
The Qt patch doesn't help here.
