Duplicate of #732

@raoulvdberge Do you need a profile from my server, or is the above enough to determine / reproduce the issue?

Your profiling report is still welcome! You can post it here, if you want.

Is it better on #732 or here? I'll try and generate a report tonight or tomorrow night.

Here is fine.
