the configuration. Notice that the redstone on the glowstone is powered even if the repeater is not. No redstone signal is coming from the top (glowstone towers only let the signal travel upwards)

Yep, still does it.

I updated mi jre and tested it on the website (i uninstalled the old version).
To be sure, I redownloaded my .minecraft folder;
Here's the new crash log: http://pastebin.com/rcBRXLVB
Also, now the report says that my java version is:

Java Version: 1.7.0_13, Oracle Corporation

I noticed that in the report i wrote 'While a repeater is facing a piece of glowstone' but, actually, it faces a piece of wool, that has got a redstone wire on top.
I added a pic that shows the configuration.

how did my java version regret so much? I remember that i had V 7 or something few days ago.
I'm going to update and try to recreate the bug.
