Bug 436450

(If this isn't the appropriate product to file this bug under, feel free to change it to whatever's more appropriate)


SUMMARY

A KDE build via kdesrc-build, when started with all of the proper exported paths, should always look in the chosen installation prefix. However, as per https://bugs.kde.org/show_bug.cgi?id=436435, the startplasma startup process will, for whatever reason, will end up calling "/usr/lib/systemd/user/plasma-krunner.service" instead of "/run/media/valmar/DataSSD/kde/usr/lib/systemd/user/plasma-krunner.service".

As a weird consequence, the system KRunner searches in kdesrc-build install prefix for its plugins, and Milou, and crashes due to incompatible versions, and symbol lookup error in Milou's case.

To run my kdesrc-build setup, I use a .bashrc function, https://invent.kde.org/-/snippets/1623, which calls this script, https://invent.kde.org/-/snippets/1624 to actually start Plasma.

Also, here's the KRunner error output from journalctl: https://invent.kde.org/-/snippets/1622


STEPS TO REPRODUCE

1. Build KDE suite via kdesrc-build
2. Start kdesrc-build Plasma session
3. Search in KRunner until you get some search results
4. Crash

In your process viewer of choice, you should observe the KRunner process having the command name of "/usr/bin/krunner" instead of "/run/media/valmar/DataSSD/kde/usr-2021-04-30-17-35/bin/krunner" or the like.
