Arch Linux

Now reported upstream: https://bugs.kde.org/show_bug.cgi?id=360056

Please try again with yakuake 3.0.2-2

Still get segfault with
$ yaourt -Qi yakuake
Name : yakuake
Version : 3.0.2-2
info from KDE crash handler attached.
Thank you.

Still crashing. Additional info: I am using IceWM as a window manager, no other KDE/Qt application.

3.0.2-2 is also crashing here (note: tried yakuake-git and that's also).
I attached my crash report as it contains a bit more information then the one before.

The kglobalacceld thing already occurred with previous version of yakuake - without crash (see the second part of this comment). I just did not paid attention to it beforehand. It is most probably unrelated to the crash. Now, I installed the bug reporting tool drkonqi (via plasma-meta package) and I set up my IceWM session to run kdeinit5 and kglobalaccel5 at startup.


New steps to reproduce and actual results (yakuake-3.0.2-2):
----
$ yakuake
KCrash: Application 'yakuake' crashing...
KCrash: Attempting to start /usr/lib/drkonqi from kdeinit
----
The backtrace is attached as a file.


For the record, downgrading to yakuake-2.9.9-5, without kglobalaccel, there is no crash but it prints the following messages:
----

Using kglobalaccel, yakuake 2.9.9 runs as well:

After installing kde-base-debug from the qt-debug unofficial repository and installing yakuake-debug from the attached PKGBUILD and yakuake-debug.install files, I obtain the attached backtrace with full debug symbols.

I also experienced this bug and have reverted back to yakuake-2.9.9-5 in the interim.

I tried to reproduce, without success. I'm using Yakuake extensively everyday though.

Could you give the set of options you use? Plus the exact thing you do when the bug is triggered?
Do you have everything date?

Thx

For me, this resolved magically today. I had IgnorePkg'ed yakuake since 2.9.9 due to this bug (host 1). New installation (host 2)---same segfault. Just to reproduce this behaviour, I upgraded host 1 (yakuake 2.9.9->3.0.2-3) and it just worked again. For host 2, I installed extra/konsolepart4, yakuake got running, and I removed konsolepart4 again, yakuake surviving. I hope for everyone with this issue the same bad reproducibility (-:

Speicherzugriffsfehler (Speicherabzug geschrieben)

persuaded me to install kmenuedit, hence essentially a full KDE destop (though I don't need it): and the segfault vanished. Sounds like unmet dependencies on some KDE-internal library, which isn't covered by the package.

It now works flawlessly using a fresh user profile after running kglobalaccel5.
Latest crash occurred in September, thus yakuake-3.0.2-3 did not fix it, it was a dependency issue.
Either (most probably) kglobalaccel updates solved it or some other package installation incidentally fixed it.
