Hi,

my kmail crashes when I try to view messages in my IMAP directories.

I would write a bug-report but can't get enough debugging information since I don't know which packages are needed.
The KDE assistant only suggests to install kmail.
I am working on up-to-date KDE-neon, where I also installed kmail-dbgsymm, but that doesn't seem do it.
Below is the console output.

Any help appreciated!

You may want the debug packages of akonadi and kdepim-runtime at the bare minimum. Messagelib and pimcommon would also help. Also kdepim-addons as well.

Thanks. I assumed you meant messagelist and obtained some debugging information now.
However the dialog says that it isn't good enough.
It wants debugging information for

/usr/lib/x86_64-linux-gnu/libKF5CoreAddons.so.5
/usr/lib/x86_64-linux-gnu/libQt5Core.so.5
/usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5
/usr/lib/x86_64-linux-gnu/libKF5AkonadiCore.so.5
/usr/lib/x86_64-linux-gnu/libKF5MessageViewer.so.5
/usr/lib/x86_64-linux-gnu/libQt5Gui.so.5

which I can't locate ...

MessageVIewer is provided by messagelib; CoreAddons by kcoreaddons; AkonadiCore by akonadi. You don't need the Qt ones most of the time, they're also huge in terms of disk space. What distribution are you using?

I am using kde-neon. Unfotunately, I can't find packages for debug symbols with that name.

Those are the source package names. In Neon they should be something followed by "-dbg". Try searching for packages with "akonadi" and "dbg" in their names.

I have libkf5pimcommon5-dbgsym , kdepim-runtime-dbgsym , akonadi-dbg , but for messagelib the only package I find is kf5-messagelib-data.

I'll move this to the Neon forum, there might be more people able to help.

In case someone has the same issue:

I still don't have the required debug symbols, but found out that the bug is related to the header of the message view.
If I choose one of the headers (View->Headers) that doesn't load a thumbnail image from the addressbook, those crashes don't happen.

Hi highsciguy!

I have the same problem as you with KMail. I have tried your suggestion with all different headers but I doesn't work. It still crashes when a try to view the e-mails in my list.

Have you used any kind of custom header?

Thanks,
Luke

Yes I have tried all installed standard headers (not extensively).
'Long Headers' is definitely stable for me.
As mentioned, I found that those which show a picture from the addressbook crash my kmail.
If I use those I also occasionally see notification messages from the tray that something is downloaded, and than the crash.
You might well see a different bug of course.

I just installed Kmail also and I have never been able to view my messages either. I have gone to youtube and followed instructions for installation and setup and I too cant view messages without crashing. I just went and used Geary mail and it works fine. I actually like the way KMail LOOKS but oh well.

I have tried the solution suggested by highsciguy but KMail still crashes for me, not matter which header type I have selected.

I found KMail quite buggy in KDE 5. It used to do its job quite well in KDE 4.12. I now rely on Thunderbird but it is a shame that KMail does not work properly as it supposed to be the optimal e-mail client for KDE.

Are you using the nouveau driver?

The latest KMail versions use QtWebEngine for the message display, which crashes on nouveau because nouveau doesn't like multi-threaded applications using OpenGL.

Installing the proprietary nvidia driver should fix that.

Hi Wolfi23,

You are right, I have uninstalled the nouveau driver and installed the Nvidia drivers and problems with KMail have gone.

In any case I think this issue should be also reported as a bug because KDE Neon comes with the nouveau driver by default so other users might be experiencing the same issue.

Thanks for your help!
Luke
