"Go to symbol" crashes with SCSS

Using CMD+R for "go to symbol" in a SCSS file works fine, I start typing a class name and it jumps to the according symbol. However, if I have a typo and want to change what I've typed so far, as soon as I hit backspace, Sublime crashes. I do not know if this is core or plugin related and I have never reported a bug before, so please point me to the right direction to make this a prober bug report.
