Hmm... I'm not sure if I can narrow it down too much more, based on that list of programs/sites.
Did it cause any of your programs to close unexpectedly? Or, when you received that error, did it prevent you from being able to open up a specific file or web page? If not, then I would think that it probably isn't anything major, and it's likely not anything that you need to worry about.
Typically an "application-type" error (i.e. an error in a program such as Word, or Excel, etc.) won't provide you with a specific line number, and will usually kick you out of the program once you acknowledge the error message. This leads me to think that it was probably more along the lines of an error on one of the web sites that you were visiting at the time. It could have been something as simple as a typo in the underlying code on one of the sites, or possibly a problem with a script that one of the sites was trying to run. Those errors are not uncommon, and are usually corrected pretty quickly by the person(s) that publish the site.
Keep an eye on things, and if it happens again, see if you can figure out exactly what program is reporting the problem. A lot of times, the top portion of the error message itself will contain the name of the program that encountered the error. If we know that, and what you were trying to do at the time, we may be able to dig a little deeper.
Sorry I can't get any more specific for you.
Good luck!
