Konsole 21.08 Segfaulting

After full updrade, Konsole 21.08 won’t launch for me on virtual and bare metal systems, just insta-segfaults, had to downgrade back to 21.04.3.

[  111.655923] konsole[1221]: segfault at 8 ip 00007f6ea4f93f21 sp 00007ffc94d42f80 error 4 in libQt5Gui.so.5.15.2[7f6ea4f32000+4dc000]

Anyone else experiencing this?

Dr Konqi output.

Yakuake working fine, which depends on konsole, so :man_shrugging: .


Not just me … also reported upstream.


Current workaround is to downgrade to 21.04.3 and wait for fix.

Nothing mentioned about it (yet?) on KDE bug tracking system: Bug List

Works fine on my end.

Thanks for the link, this issue with a temp workaround has now been reported.


To get Konsole to work again, you can edit ~/.config/konsolerc and set 


When launching konsole could be expecting previous geometry info that doesn’t exist if you don’t have this setting on.


I saw that one also before but perhaps I didn’t read carefully enough to connect the dots. Thanks!

I don’t have that, and konsole works…



I’m guessing the window geometry was already set correctly so there was no funny business with the new version of konsole getting incorrect geometry and segfaulting. I think this is the case with a vast majority of users, and that’s why this bug slipped through quality control.

They couldn’t see that one through all the bloat :rofl:

P.S. We need a bloat control department :male_detective:

Try setting that value to false and see if you get the same segfault.

No segfault… works as expected.

Works for me also.

Apparently, it works if you are saving window geometry. That is probably why it works for some people and not others.

Patched and released with konsole 21.08.0-2, along with the toolbar bug everyone was screaming about on reddit.
