Auto-proxy via file broken? Fix for crashing Tweetie and iTunes

Question

After upgrading to 10.6, Tweetie and iTunes would crash on launch.
I was using a proxy.pac file to automatically set up a proxy when I'm at home (I've got Squid running on my file server). Disabling this (System Preferences > Network > Advanced > Proxies > Automatic Proxy Configuration) made them work again.
I noticed slowdowns with Firefox and Thunderbird as well, hopefully disabling the proxy will fix that issue as well.
Here's my proxy.pac file:
function FindProxyForURL( url, host ) {
if( shExpMatch( host, "*.local" ) ) {
return "DIRECT";
} else if( url.substring( 0, 6 ) == "https:" ) {
return "DIRECT";
} else if( isInNet( myIpAddress(), "10.0.0.0", "255.255.255.0" ) ) {
return "PROXY10.0.0.12:3128";
} else if( isInNet( myIpAddress(), "192.168.0.0", "255.255.0.0" ) ) {
// It's there somewhere..."
return "DIRECT";
return "DIRECT";
}

Thanks for the thoughts.
I'll look through both your suggestions.  It's not really what I'd call a split library, as the /media/music/... folder structure contains both the music files themselves and the iTunes Library folder.
If the folder with the library files (normally iTunes) contains the designated media folder (normally iTunes Media) which in turn contains all media, including any iOS apps and clickwheel games, in any structure you like, then the library is portable. If it doesn't meet the criteria then it is split. Portability comes from the relative relationship between library location and media folder location. iTunes will adjust for a similar change in the root path to both that happens simultaneously, but otherwise expects media to remain on exactly the same path each time it runs.
In context it would seem as if /media is your current media folder in which case moving the library files (see the tip) up to the root of the drive would make the library portable, if not consistent with the common names for the folders. Having accessed the library database at /iTunes Library.itl you should find that you can now close iTunes, change /media to /iTunes Media and reopen without breaking the library. You should then be able to close iTunes, create a new empty folder /iTunes, move the library files and media folder inside /iTunes and access the library at /iTunes/iTunes Library.itl. This would now be a completely portable library with standard names for the principal folders.
iTunes for Windows doesn't provide access to the last known path of missing files so it isn't possible to use a simple string replacement technique to fix things up. If you were to use my script you'd probably need to run it against the media folders; Artists, Pop, Rock, etc. in turn, looking for the content located within each.
