I'd love to get feedback, whether anybody else can reproduce this bug.
1. Draw a path.
2. Apply any extension with options to it.
3. Select the path again.
4. Run "Previous Effect Settings..."
For me it's:
5. The effect automatically executes with same settings and *then*
shows up the dialog with options.
I can reproduce this on Hardy and any recent 0.46/trunk code snapshot
10 out of 10 times.
