I am using the Latest version of OS X 10.10.4 and 1Password 5.3 and 1password crashed (probably first time it has ever crashed in my life of using 1password) so then I wanted to submit the bug report. Well it appears the bug reporter is now frozen as well. I have attached a screenshot below.
Let me know if you need any other info from me
1Password Version: 5.3 Latest MAS
Extension Version: Latest
OS Version: OSX 10.10.4 Latest
Sync Type: Dropbox
