Line 101 is
$returnargs = $func($arguments);
$func is the function being ran by the hook.
A plugin hooking with an empty function name is causing this. Try disabling and re-enabling each of your plugins, or look through your plugin files for something like this:
$plugins->add_hook("some_hook_name","");
What version of PHP are you using out of curiosity?
Installed any plugins recently? Which ones?

Interesting. I'm guessing we should add some protection for that, but then again - plugin authors who have such a thing in their files need shot in the foot
Omar, if you find such a line, just comment it out by putting // at the start of the line.
Try to set NO for all plugins from settings and notice if it still occurs, that way you can spot if any plugin is prolly causing this.
