I can't confirm this behavior. Mounting an iso doesn't crash docky for me at all. I see where it's crashing in the code, but have no idea why it would even crash there. Can you give me some info about the iso? I've got some other work to do on the mounter anyways, so I might fix this in the course of my other housekeeping soon. I'll update the bug report when I know.
