Unable to clone a Mercurial repo by URL

I'm trying to clone a mercurial repo (hosted by Kiln). It's been working fine for months, but recently I replaced my workstation with a new iMac downloaded and installed the latest SourceTree and now this:

Error calling askpass for username: 2017-05-29 20:42:02.381 SourceTreeLogin[13924:1807324] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSPlaceholderMutableString initWithString:]: nil argument'

*** First throw call stack:


I'm at a loss on how to troubleshoot this. I'm using the embedded mercurial, but have installed (via homebrew) the lastst and have no problem cloning the repo in question from the terminal.
