OK now it all makes sense again. Sorry guys.
On another note I found a nifty tool for memory profiling.

Let's see what we can do with that

Bug description:
I'm seeing with standalone Sezen that after running it, mem usage of the zeitgeist-daemon process goes up from ~13MB to ~40MB, this is understandable as when Sezen is starting, it does one big query where it asks for everything grouped by most recent subjects and in my case this returns ~11 thousand events, so the extra 30MB can be explained by allocating memory for the DBus reply.

Still, my question is whether Zeitgeist should be at mercy of the applications, where nothing prevents them from spiking the memory usage of the core process. (I already saw a couple of times zeitgeist using 80-100MB of memory on my system). Perhaps there's a way to tell python dbus to free its buffers?
