generic question regarding the network theme

hi there.
I just gave the newest network theme version - 1.5.2 a new try on my wp 3.1 multisite enabled.

it kinda works except for one issue:

on my front-page and only there, the page stops loading, shows the same issues as if I had a rogues plugin or broken php call. I am sure it stops laoding as the menu bar I have on top of my sites is not showing and neither is my footer. so there must be some wrong code here or in one of my plugins but my error log doesn't show anything

this is all I can find related in my error log:
