Here's what I found as to how the bug works:
1. Restart system
2. Right click on the xfce desktop or any icon on it
3. Click on Properties
4. It works fine & the system will not encounter the bug again in this session.
Here's how to see the bug:
1. Restart system
2. Open a folder anywhere (Desktop or launch Thunar)
3. Right click on anything (not a folder, it must be a file) & click on Properties
4. Thunar crashes
So, as soon as you do a Properties on the Desktop or anything on the Desktop you will rectify the Thunar crash scenario for the current session.
Theses are the dependencies installed from AUR.
I'm showing the same result with Thunar on XFCE using gtkhash-thunar 1.0-1 - Immediate crash of Thunar when a file's properties are accessed. I downgraded back to my previous AUR package gtkhash-thunar 0.7.0-3 which restores access to properties and the gtkhash plugin works. Issue is with the new build of the plugin. I also run Thunar on Cinnamon and the issue is NOT present using Thunar with gtkhash=thunar 1.0-1 on Cinnamon, the crash is only occurring on XFCE. Noting Phil's find that "initializing" it via the desktop first sorta stops it from happening, and the fact that it doesn't happen on Cinnamon leads me to thinking it's something related to the XFCE desktop.
With theses packages installed a Properties click with "Thunar as root" will crash even AFTER the desktop workaround has been employed. So the workaround is not a complete workaround.
Thanks for the reports. gtkhash upstream is investigating.
Is this fixed?
Working now in gtkhash-thunar 1.1-1 & thunar 1.6.11.
Anybody else confirm this can be marked as resolved?
I can confirm this is now working properly on gtkhash/gtkhash-thunar 1.1-1 and Thunar 1.6.11. Tested on both Manjaro and Arch XFCE, several machines/ different architectures. Have not come across any issues so far.
thx for the positive report :)
