Replication instructions: 1- Open Thunar and go to any folder (ex Desktop); 2- Create a new folder; 3- Drag and drop the created folder into the shortcuts panel; 4- Rename the folder (not the shortcut) to something else; 4- Close ALL Thunar instances (or logout); 5- Reopen Thunar. Shortcut is gone.
I was able to test and confirm this with: - Thunar 1.6.2 (64-bit) - Thunar 1.6.2git-dfe9593 (64-bit) I was further able to solve this issue by installing the gtk murrine theme engine. On ArchLinux the package is available as gtk-engine-murrine. I am pretty sure other package managers provides this. If you are getting the following error message when running Thunar, then this may be the problem: (lt-thunar:11371): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
Strange bug. Closing as invalid due to configuration problem. Please reopen if still reproducible.
