Code Inspection results can't be displayed

Since a few days, we can't access code inspections results in TC anymore. When clicking on "View full report", it says "Loading" forever.
In the log file, huge stack traces can be found that eventually show a NPE.

Here is what a freshly installed TC 3.1.1 shows in its log file, but we encounter the same error on the 3.1 version we have in production use:

ERROR - jetbrains.buildServer.SERVER - Error in JSP, request dump:

The problem might be related to updating from IDEA 7.0.2 to 7.0.3, however we aren't 100% sure if that was the same same point in time when this issue first occured.

Any help is highly appreciated as Code Inspections are currently unusable for us.
