Redmine

After upgrading redmine to latest version and upgrading ruby to 1.9.3 I was getting this error in some projects roadmap views:

Completed 500 Internal Server Error in 43.5ms

undefined method `size' for 9.307692307692308:Float

i rawly fixed it adding a "try catch" to bigdecimal_segfault.rb (i'm not a ruby developer so there's surely a better method to check if the object has the size method, anyway i post my fix here for reference because it seems to make it working:
