This bug was fixed in the beta. Go install that, and make sure all of the users do too.
I'll update only when IC2 comes out officialy
Dude, what? You are going to use a slightly bugged version of IndustrialCraft just because 1.108 hasn't been "officially released" yet?
Uhm, the 1.108 release is from the dev team, its just an open beta, meaning its not promised to be 100% stabile, could bring undesired effects to the game, could also be rock solid, with small bugz requireing a swift kick in the nutter.
As such, with all mod updates, make sure to have a backup of the old file, and if you utilise a backup system with your worlds, make a current backup before jumping up to 1.108, other than that, i can say i've installed it on a fresh server on a friend of mine, and atm were 3 people running around with this, and a few other mods and so far i havnt encounter bugs 
Admitted, i havnt gotten back up to quantum stage yet! But i am working on it
