STEPS TO REPRODUCE 1. Install Kate from the nightly Flatpak repo (https://cdn.kde.org/flatpak/kate-nightly/org.kde.kate.flatpakref) 2. Activate the "Git blame" plugin 3. Open a file in a git repo 4. Click on any line of code 5. Click on the faded text to the right of the code that shows the git details of the commit that last touched that line OBSERVED RESULT Nothing visibly happens in the app. However a process named `flatpak-session-helper` is spawned and rapidly consumes 25% of a CPU core. Killing it results in Kate showing an error message saying: > [14:35:33  Git Error] Git blame, show commit failed. EXPECTED RESULT A popup showing the commit details SOFTWARE/OS VERSIONS Operating System: KDE Linux 2025-08-21 KDE Plasma Version: 6.4.80 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.1 Kernel Version: 6.16.1-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 16 GiB of RAM (14.9 GiB usable) Graphics Processor: AMD Radeon 780M Graphics
Git commit 537542367a509055c73670da94feceac6b4add59 by Waqar Ahmed. Committed on 26/08/2025 at 07:32. Pushed by waqar into branch 'master'. Fix infinite loop in git blame It was assuming that the commit hash is always arg[1] which is not true in the case of flatpak where the process is invoked via a helper. So instead, use better logic to find the commit that the process result is for.

Hmm, I'm not seeing this fixed in last night's nightly build. I still get the same result: no inline popup about the commit details, and flatpak-session-helper consumes CPU until killed.
> 1. Install Kate from the nightly Flatpak repo (https://cdn.kde.org/flatpak/kate-nightly/org.kde.kate.flatpakref) I just installed kate from the url you gave: > flatpak install --user https://cdn.kde.org/flatpak/kate-nightly/org.kde.kate.flatpakref and it seems to work here.
You're right! I had a locally-built Kate that was masking the system-installed nightly version. I can confirm the issue is fixed now. Thanks so much!
