Hi,  
i got very strange problem connected to tests in Rails. I got the same  
application code version as my team has, and on their computer all tests  
pass, and on my laptop (debian 5, ruby 1.8.6/1.8.7 (tried both), rails  
2.3.2) i got more then 50 errors - majority of them is variations of  
“NoMethodError: private method `gsub’ called for 117681882:Fixnum” error  
in controller.

Anyone know how to fix it/has this problem before?  
I reinstalled ruby and rails about three times, clearing gems etc every  
time but with no effect…

Problem Was sqlite as test database, setting it to mysql fix the  
problem.
