SUMMARY
Opening a new tab (either via the shortcut, button, or global menubar) results in a segfault. Backtrace:

frame #11: 0x00000001004f2e48 libkonsoleapp.24.04.70.dylib`Konsole::MainWindow::newTab() + 84

STEPS TO REPRODUCE
1. Open a new tab.

OBSERVED RESULT
Konsole crashes.

EXPECTED RESULT
A new tab is opened.

SOFTWARE/OS VERSIONS
macOS: 14.4 (23E214)
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

ADDITIONAL INFORMATION
Gatekeeper seems to be rejecting arm64 CI artifacts for some reason. This can be worked around by running `codesign --force --deep -s - konsole.app` to replace the signature, then bypassing the warning about an unsigned application.

Comment 1 deadite66 2024-03-13 19:38:31 UTC

had the issue twice the last few days on Arch plasma 6.0.1 when opening a tab.

running konsole (24.02.0) under gdb hopefully i can get a backtrace.

Comment 2 Kurt Hindenburg 2024-03-22 23:04:04 UTC

confirmed on the macos-x86_64 dmg

Comment 3 Kurt Hindenburg 2024-03-22 23:09:17 UTC

Once I removed the signature it works.  Also note that konsole that I build on macos has always worked.

codesign --remove-signature konsole.app

haven't had the issue happen again since 6.0.2 so perhaps unrelated to the mac problem.
