IMovie Unexpectedly quitting when trying to select a clip

Question

I am suspecting that I may have a corrupted project. Then again, it could just be a major problem with my Mac. At one point during my import, iMovie unexpectedly quit. I was able to reopen the project and continue the import. Once the import was complete, I attempted to click on a clip, and boom! iMovie unexpectedly quit. I reopened, and was asked to move the clips to the clipboard and all went well. I even was able to save the project. Still any time I select any clip, iMovie unexpectedly quits. For reference, here is a portion of the dialog of the crash:

Any suggestions on where I might begin solving this issue?

My standard list of things to do first for these weird sort of problems, but I also tend to run these before I go to burn an iDVD project just to be safe. Keep in mind this list represents the programs I tend to use. I am running Panther (10.3.9) so Tiger users might want to check the below list for compatibility. There are several alternate programs that do the same things with some combining the functions of some of the ones below. So everyone has their favorites, but here are mine...
Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system, especially any external drives that you use for iMovie and iDVD projects.
Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
Run Cache Out X (free download) to clear all system and application caches.
Reboot your Mac (after running Cache Out X you are given the option to restart the machine).
If you still can not get it to run correctly, next thing to try is to throw out the iMovie preference file (don't forget to change back those preferences you want different from the defaults next time you run it). If it still doesn't work, then I would suggest you reinstall iMovie.
