Simply, the Exec option in "/usr/share/applications/sylpheed-claws.desktop" should be "sylpheed-claws", not "sylpheed". Reproducible: Always Steps to Reproduce: 1. Install sylpheed-claws-1.9.13-r1 2. Run it from, for example, GNOME or XFCE (through the apps-panel) Actual Results: "sylpheed" executable is not found. Expected Results: run "sylpheed-claws", not "sylpheed"
Can't reproduce that here, I don't see a non-claws entry anywhere (with both 1.9.13-r1 and 1.9.15)
