You need to fix the associations for the inode/directory mime type on your system (check on Google).
Timeshift executes xdg-open to open snapshot folder in file manager. xdg-open uses the default file/folder associations on your system. Your system seems to be configured to open with Gwenview. You need to change that to Dolphin.
I have a problem, here are some logs, I hope it is useful: Kubuntu 18.04 Timeshift 18.6.1

According to the error message, your system does not support running file manager (Dolphin) as root. You won't be able to browse the snapshots.
I had the same problem on Lubuntu: Pressing the browse button opens Audacious. The reason is that xdg-open is not really meant be used by the root account. Root is no desktop user.
Timeshift runs under the root account and xdg-open finds no .desktop file for mime type
inode/directory, because the root account has no .desktop files at all.
xdg-open then defaults to /usr/share/applications/defaults.list which
happens to be the unmodified "gnome" list in Lubuntu, containing the following line:
inode/directory=nautilus-folder-handler.desktop
But on Lubuntu the nautilus-folder-handler.desktop item does not exist. Lubuntu does not use nautilus. Apparently the system then takes the first application that has inode/directory in its accepted mime types, in my case Audacious.
The problem could be solved for Lubuntu by changing the offending line in
/usr/share/applications/defaults.list to:
inode/directory=pcmanfm.desktop
but I am not sure if that survives possible updates of the system.
A better solution is to add a new defaults.list file to the root account:
/root/.local/share/appplications/defaults.list
containing only these two lines:
inode/directory=pcmanfm.desktop
x-directory/normal=pcmanfm.desktop
@teejee2008 xdg-open man page said that xdg-open shouldn't be run from root too (https://linux.die.net/man/1/xdg-open). Looks like you run xdg-open through the pkexec for files/websites (https://github.com/teejee2008/timeshift/blob/master/src/Utility/TeeJee.System.vala#L356), but not for directories(https://github.com/teejee2008/timeshift/blob/master/src/Utility/TeeJee.System.vala#L370). Why?
@teejee2008 can you check this please?
Files in the snapshot directory are owned by root. Opening it in a file manager running as a normal user is not useful.
I'll change this so that the file manager is opened directly instead of using xdg-open.
For now, just before it is fixed on v19.06 as @teejee2008 said above (June 30, 2019 is the latest planned day for release), you can do the workaround commented by @willem179.
I share with you a little video of my issue on KDE neon 5.15 (it opened VScode instead of the file explorer) and the corresponding steps I made to fix it:
is this still due to be fixed for KDE in a few days ? I have not been able to use timeshift for a long time and am looking forward to using it again. I have tried the workarounds but Manjaro KDE does not allow dolphin to run as root so none of them worked. Thx.
This is fixed. Duplicate of #186
After selecting a specific backup and after clicking the browse button, the default file browser Dolphin will not open, but open the Gwenview image viewer.
Steps needed to repeat the error:
I also checked the manjaro and there is the same problem, also the problem concerns more the environment, not the system.
