NSMutableDictionary & Strings - Weird, weird problem

Hey guys

In my program, I have a NSMutableDictionary that I save to a .plist,
and reload on startup.  I'm having an extremely odd problem with it.

Some of the strings I want to save are strings that look like URLs,
but they are strings.  It seems to save them fine, but when I load the
Dictionary back from the harddrive, it crashes out on me and gives me
an error:

2006-06-30 16:21:56.243 AMP[3509] http://www.mp3car.com/vbulletin/
2006-06-30 16:21:56.252 AMP[3509] An uncaught exception was raised
2006-06-30 16:21:56.271 AMP[3509] [<NSCFString 0xa3cb300>
valueForUndefinedKey:]: this class is not key value coding-compliant
for the key SYSTEM_VOLUME.
2006-06-30 16:21:56.332 AMP[3509] *** Uncaught exception:
<NSUnknownKeyException> [<NSCFString 0xa3cb300>
valueForUndefinedKey:]: this class is not key value coding-compliant
for the key SYSTEM_VOLUME.


(But SYSTEM_VOLUME isn't the related key. The related key is something totally different - and SYSTEM_VOLUME, along with every other key look perfect when I view the .plist in an editor)

Here is a specific string it crashes on:

http://www.mp3car.com/vbulletin/
It crashes on that, but the following it has no problem with:
http://www.mp3car.com/
Nor does it have a problem with this:
http://www.aychamo.com/?page_id=4

So what is it in /vbulletin/ that causes it to crash?  I can't for my
life figure this out.  I've been playing with it all day and feel as
though I've hit a wall. Whatever it is in that string, it sure makes
it crash.  This is the line of code I use to set the string value into
the dictionary:

[preferencesDictionary setValue:[browserAddress stringValue]
forKey:@"BROWSER_FAVORITES_1"];

(browserAddress is just a NSTextField)
And then I just save the dictionary to a file..  seem's pretty harmless to me.

Does anyone have an idea where I should start looking??
Thank you
Bobby
