Text Formatting Bug in Task Descriptions

Hi all,

I'm encountering a bug when copying / pasting into task descriptions. If I copy formatted text (especially bullets / hierarchy), I can paste into the task description just fine, but if I add a checkbox and then paste the text following, it crashes the window.

I wasn't able to replicate this in Chrome or IE, but I can recreate it every time in Firefox. Is anyone else having this issue?
