I notice the issue yesterday when mounting a USB hard-disk with the KDE panel's removable drive icon, and Gwenview launched instead of Dolphin.
I have went into KDE settings to switch the default file manager to dolphin to no avail. Restarting again shows that Gwenview is once again selected as the default file manager.
How do I force the system into using Dolphin as the default file manager again?
Correction. After further testing, I found out Gwenview is being reselected as the default file manager within the same session! Closing System Settings after selecting Dolphin as the default file manager does not work because re-opening the relevant settings page again shows Gwenview was once again chosen as the default application!
