I have the same issue, in my case I've determined that the lookup fails whenever Adobe Creative Suite 6 is installed. I don't have a final solution yet, (I set up a case with Apple on Friday but won't be back in the office until Tuesday to follow up), but uninstalling CS6 allows the application list to build normally. Of course, I can't roll out Profile Manager until I can add CS6 to the approved application list but at least I can set up all of the other application-related options while I wait.
To see if you're situation is the same as mine, here's what happens when I open the Application list and get the "A Server Error has Occurred" message.
The following events are logged:
- ReportCrash[773]: DebugSymbols was unable to start a spotlight query: spotlight is not responding or disabled.
- ReportCrash[773]: failed looking up LS service ( scCreateSystemService returned MACH_PORT_NULL, called from 3) SetupCoreApplicationServicesCommunicationPort, so using client-side NULL calls.
- ReportCrash[773]: LaunchServices/5123589: Unable to lookup coreservices session port for session 0x186a0 uid=0 euid=0
- ReportCrash: Saved crash report for ruby[202] version 83.4 to /Library/Logs/Diagnosticreports/ruby_2012-10-17-124804_SERVERNAME.crash
Events #2 & #3 are logged multiple times before Ruby finally crashes.
Below is the start of the crash report:
