Subject: Exception in Rails

I used to get a lot of FloatDomainError exceptions with rails.
Seems like the problem is with
vendor/actionpack/lib/action_controller/benchmarking.rb.

Changing line 46 from:
  " | DB: #{sprintf("%f", db_runtime)} (#{sprintf("%d",
db_percentage)}%)"

To:
  begin
    " | DB: #{sprintf("%f", db_runtime)} (#{sprintf("%d",
db_percentage)}%)"
  rescue
    " | DB: #{db_runtime} (#{db_percentage}%)"
  end 

Seems to work.


Cheers,
Assaph


ps. Using Rails 0.5.7 with SQLite on WinXP.
