Gmail only threads based on the subject line. If the subject line is 
changed, it breaks the thread. Google Groups does not do this, and I 
wish Gmail worked like this: when the subject line is changed, the 
message is displayed in the same thread, but a yellow is noticed with a 
message like "Jeremy changed the subject line to 'Foo Bar'".

Thunderbird and Evolution thread correctly regardless of the subject line.
