[Adium-devl] AppleScript has some problems.

[Matt Handley]

In r20893, files were merged from trunk to my applescript branch. When
this happened, something very subtle changed about the way Adium
works, and now AppleScript cannot control Adium whatsoever. Any script
that attempts to get any information is met with an raised exception
(NSEvaluationScriptError: 3). Other custom verbs (like go <status>) do
nothing. So something is extremely wrong.

However, it doesn't really look like it's any change to the
AppleScript components itself: the sdef did not change, Adium_2.plist
still has the correct keys to enable scripting, and the Obj-C code
looks fine, too. Also, when you enable debug output for all apple
events (defaults write NSGlobalDomain NSScriptingDebugLogLevel 1),
it's clear that the error is occurring before Adium's code is being
executed (somewhere in the AS-Cocoa bridge).

So, if I were to guess at what's happening (and this is a mostly wild
guess), I would suspect some memory weirdness is overwriting some key
piece of information that AS needs to respond to the script command
correctly.

On a potentially related note, whenever an command is run (regardless
of what it raises or returns), at some point in the future, Adium
crashes. The backtrace usually has something to do with Jabber. He's
one I thought to copy to a file:

Anywho, this terribly important (for AS to work) bug needs to be
squashed. It's ticket # is 7968 (http://trac.adiumx.com/ticket/7968).

Any help you can give me to help track this down would be much appreciated.
