No matter which commit I compile (I tried the most recent/a few months back/beginning of year), uzbl-browser starts as expected, but hangs (idles?) at 10%.

• The target uri as provided via command line is displayed.
• PID is displayed.
• Key commands like switching to insert mode or hiding the status bar and the like work.

Note that, for my tests, I created a new user with an empty home directory, ensuring that the original config file is used.

Since about February I did not compile uzbl. I did now as my existing installation was failing after upgrading some packages on the system. There were error messages about icu which had been updated from 59.1-2 to 60.1-1. (Downgrading just this package alone would cause other errors still preventing uzbl from being run.)

Please let me know what else I may provide in order to track down the cause of this issue.
