Open Folder opens the wrong application

[bgoodr]

I'm running Deluge 1.3.3 on a 64-bit Debian Linux desktop. I'm running it under StumpWM window manager (basically, not Gnome and not KDE). The window manager should not matter in this context anyhow but here goes:

Below is a screenshot of the context menu that is displayed when I right mouse click over a torrent:



So, when I then click on Open Folder, what I expect to see is some file browser (e.g., under GNOME it should be Nautilus or something). But instead it opens up Audacious which is a music playing and editing app. So I looked under Preferences but did not find any setting to change the application to use.

Where do I change this to open up the file browser instead?

This is the version reported by deluge installed by Debian package manager:

deluge: 1.3.3

Thanks,

This is not a Deluge issue, it is an OS issue with xdg-open so you need to ask other Debian users how to verify/change association.
