A few things: First is what version of QS are you using? I'm using b56a7, and can't test how it works on other versions.
Second is I changed something that might have been the bug. The third is if you don't have Growl that might cause the crash. So download these http://tr.im/D4J6 one is clearly labeled for use without growl. If you have Growl I'd use that one. Otherwise they both have the other fix. QS doesn't crash for me using these.
