I have no clue. If I'm not mistaken, none of the packages that provide that file
has changed recently.

To make sure, could you:

$ dpkg -S libgtk-x11-2.0.so.0.2400.4

...and then run `ls -l <full_path_to_each_occurences>' and post the results
here. For example, here's what my system shows:

jaska at ardbeg 02:12:21 ~$ dpkg -S libgtk-x11-2.0.so.0.2400.4
libgtk2.0-0: /usr/lib/libgtk-x11-2.0.so.0.2400.4
ia32-libs: /usr/lib32/libgtk-x11-2.0.so.0.2400.4
jaska at ardbeg 02:12:44 ~$ ll /usr/lib/libgtk-x11-2.0.so.0.2400.4
-rw-r--r-- 1 root root 4461064 2011-04-14 21:15
/usr/lib/libgtk-x11-2.0.so.0.2400.4
jaska at ardbeg 02:13:19 ~$ ll /usr/lib32/libgtk-x11-2.0.so.0.2400.4

I have no idea how those plugins might have affected such a library, but better
safe than sorry. You can check your dpkg log at: /var/log/dpkg.log

It should be quite obvious if you start from the bottom end, you should see the
latest installed packages.

Might even give us a look, unless you have anything you don't wanna share with
us :) by:

$ tail -20 /var/log/dpkg.log
