I'm using TextMate 2.0-alpha.9427 on OS X 10.8.2. Since two days, when I run a script (Python or shell script), instead of the directory of the script itself, the current working directory is something like /private/var/folders/0r/y4qmws5d2tjdkqzlb19_ny1h0000gn/T.
I think this behaviour appeared with the last TextMate alpha release, but reverting to the previous version was useless. Any ideas?
