原因

This is an OS or Java related bug/ problem. Some common causes are a RedHat Bug 1479563 or a missing fonts packages.  

回避策

Disable CAPTCHA for the time being by adding feature.auth.captcha=false to the bitbucket.properties. Note this change will require a restart. There are a few other workarounds listed in this StackOverflow article as well.  

ソリューション

Check with your Unix Admins to see if you're being effected by Bug 1479563 or missing a fonts package.
