Could you explain the conditions that cause this issue?

I understand the condition.

The issue occurs when the value of a custom field of the activity is @nil@, and the new value for the custom field in the "new" hash is unset (the value will be a blank string). As a result, the conditional expression of the if statement will be false and a project-specific activity will be wrongly created.

Setting the target version to 4.1.6.

I forgot to fix test/unit/time_entry_activity_test.rb. Reattached the patch.
