How are you searching for "def" once you've closed the find window?
Don't know how he's doing it, but I can confirm the bug. Revised steps:
- Open the Ruby language definition in the bundle editor (probably works with others as well)
- Search for “indent”.
- Close search window
- Go to the beginning of the file
- Open new file, type in def, select and hit command-E to use as next search term.
- Go back to bundle window.
- Command-G to search again, should search for def now.
--> TextMate is still searching for “indent”.
