Unable to connect to an https repository with an untrusted certificate

What steps will reproduce the problem?
1. Use "Repositories" window to create a new repository entry.  In my case, I 
am using the free repositories at assembla.com (the URL is 
https://subversion.assembla.com/svn/XXXXX)
2. Double-click on entry to open the browser window

What is the expected output? What do you see instead?
I expect to see the list of folders in the repository.  Instead I get an error 
as follows:

svn Error

Error validating server certificate for 'https://subversion.assembla.com:443':
 - The certificate is not issued by a trusted authority. Use the
   fingerprint to validate the certificate manually!
Certificate information:
 - Hostname: *.assembla.com
 - Valid: from Thu, 24 Mar 2011 19:30:40 GMT until Sun, 24 Mar 2013 19:30:40 GMT
 - Issuer: 07969287, http://certificates.godaddy.com/repository, GoDaddy.com, Inc., Scottsdale, Arizona, US
 - Fingerprint: ae:b0:b6:94:14:5f:4b:28:d2:82:68:ae:e9:18:85:b3:ea:36:ee:f2
(R)eject, accept (t)emporarily or accept (p)ermanently? svn: OPTIONS of 
'https://subversion.assembla.com/svn/XXXXX': Server certificate verification 
failed: issuer is not trusted (https://subversion.assembla.com)

The dialog simply has an OK button, with no option to just accept the 
certificate as-is (even though the error message implies that I can accept it). 
 Clicking OK just gives me an empty browser window

What version of the product are you using? On what operating system?
svnX 0.9.13, on Mac OS X 10.5.8

Please provide any additional information below.
