[dev] Check for newer versions broke

[Michael Wisniewski]

When visiting the gear -> administration -> configuration -> "Check  
for newer versions", a blank screen comes back.  In my apache error  
log, I receive this error message....

[Tue May 07 08:01:48 2013] [error] [client 50.23.65.43] PHP Fatal  
error:  Call to undefined method PEAR_Error::getName() in  
/usr/src/horde/horde/horde/admin/config/index.php on line 82, referer:  
https://www.<foo>/webmail/admin/config/

This could be something I'm doing wrong, but not sure.  I know that  
this button has worked in the past, but don't know what happened.  I'm  
running the version of Horde (horde) 5.1.0-git.  Being that this is  
the dev version, I'm thinking that this functionality is disabled to  
force the user/admin to use git.  Just thought I'd ask though...

Thanks!
Mike
