iChrono won't install
Ok, so the problem seems to be that you don’t have the MultiClutch bundle in InputManagers. 

Multiclutch allows you to assign custom keyboard shortcuts in a given app to a given gesture, for example if you wanted to “swipe” to change a tab in safari or similar.


  It works by installing a simple input
  manager that catches gesture events,
  looks to see what shortcut you’ve
  defined for it in the frontmost app
  (if you haven’t defined anything, it
  behaves in the standard manner), and
  performs that shortcut.


I don’t know what iChrono does but you might try downloading MultiClutch (the free little app) because that will surely install the InputManager, if you later “remove” it (by dragging it into the thrash), the Input Manager will stay there and your widget should be able to use it.

Check that you have 


  /Library/InputManagers/MultiClutchInputManager.bundle


… and if you do and it still doesn’t work, try thrashing that bundle (save a copy just in case) and see if you can get a new copy. 

UPDATE:
Could you create a new user and try to download + decompress + install from that user instead? Logoff and login with the new user. 

There might be some weird or incompatible bundle sitting in your user.

UPDATE 2
As an added bonus, you can try to replace your Megazoomer’s SIMBL with the original one. I think you have an old version that somehow is not Universally compatible. To those effects a version was compiled by Mathias Meyer who forked the original version.

You can find his version here (links to zip). Download and uncompress the zip and drop megazoomer.bundle into ~/Library/Application Support/SIMBL/Plugins (overwrite it!)
