Got a crash today when allowing to open a popup in blogger.com.

Did the following, not sure if it can be reproduced:
- went to comments of a blog.
- noticed the blocked icon for a popup. (blogger uses this to query your google settings, so you don't have to enter the login info at the comment area).
- wanted to make this "allow by default", so opened the settings from the taskbar icon.
- added "www.blogger.com" to domain-specific settings.
- by accident kept "javascript policy" to "reject", and did set "allow popup dialogs" to "accept".
- refreshed the blogger page.
- noticed the popup was still blocked, and tried to allow it.

Resulting crash was:
