Unable to translate - Crash with Test Tool

[risu]

After MP crashes, I get a new crash, caused by Test Tool. It crashes when Test Tool is on phase: Gathering system eventlog information...

I get .NET note about unhandled exception:
Unable to translate Unicode character \uDFB8 at index 432 to tspecified code page.

If I select Continue, Test Tool stays on position it was before, it's just sitting still waiting for response.

Details from exception:
