The Official Kiba-Dock Website - Cannot edit launchers with latest revision

Hi, I recently installed the latest version of kiba dock from the svn trunk. Since then, every time I try to edit one of the launchers on my dock (via right click > edit) nothing happens. If I try to create a new Launcher via right click - populate dock > create launcher, pressing the save button has no effect. Everything else is in working order.

Did I do something wrong in the installation? according to subversion, changes were made only to the kiba-dock and kiba-plugins folders. So I performed a make distclean on both, reconfigured with autogen.sh, and reinstalled (make, then make install as root).

edit: I ran kiba dock via terminal and tried to create a new launcher. It wouldn't let me save any edits. I clicked on the launcher, received an error message saying that it cannot find the path of the file specified. I go to remove the launcher from the dock (right click on launcher > remove) and then kiba crashes. Here is the output:

-------------------------------------

Thanks for your help!
