XFCE 4.8 panel fails to load old config and crashes

[Denis Rut'kov]

Binary package hint: xfce4-panel

The XFCE panel migrating assistant does not change xfce-applications.menu file location in /home/user/.config/xfce4 files, when converting old config.

This leads to panel crashing right after trying to open the menu.

This is xsession output:

Could you provide your old panel config please? IIRC, it's not deleted when it's migrated, so it should still be available. Without that, I can't reproduce. Thanks.

[Denis Rut'kov (dendron2000)]

Sorry it took so long. It'd be great if Xubuntu started using environment variables in config files to avoid issues like this.

If you use this config on lucid (10.04) or later, you don't have any menu because this file doesn't exist anymore... So I don't expect the migration to fix that.

Anyway, there's a bug in xfce4-panel that doesn't check if the menu file exist before passing it to garcon.
