tests problem - NoMethodError: private method `gsub' called for 117681882:Fixnum

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...

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