Comment 13 for bug 1196339

I have this issue and am using Lubuntu Trusty with the default file manager PCManFM.
If "Open Containing Folder" or "Show in File Manager" is clicked in any application with those options, I find Audacious opens rather than the file manager.
After Audacious is uninstalled, I find that Google Chrome opens instead. The issue is therefore not one with Audacious. It would appear to be a problem with the opening of folders. I suspect that the first application capable of that feat is being used rather than the file manager.
