iCal sudden extreme lag and eating up all memory in week mode

This was intented to be a question but I found out the answer by the time I finished writing it so if someone out there gets the same problem, I hope this can help them.

I use iStudiez for all my school stuff so I didn't use iCal a lot recently. However, when opening it today, everytime I tried changing weeks in week mode, iCal would lag badly and stop responding for several seconds, eating all the available RAM in the process. I tried to force quit, but the problem reappeared every time.

Turns out iCal doesn't seem to handle "long" events very well. I had a "Nothing" event starting on December 21st, 2012 and ending several years later, and deleting it caused the lagging to stop. I guess iCal tries to load the whole event when it appears in the week view.

Hope this post helps someone or alerts Apple to issue a fix. (I use the latest version of iCal on the latest build of OSX, which as of today is iCal 6.0 on OS X 10.8.2)
