On hindsight, it seems that a flash file may have been contributory:
apt-cache policy flashplugin-installer

Bug #647969 and bug #648993 look very similar to this one, they might be duplicates.

[Robert Roth (evfool)]

Bug #638552 is also very similar. Is this a problem with ndispluginwrapper, or with flashplayer? The libflashplayer appears in all bugs like this one, it might be causing this.
