Ok, I could just successfully clear the history, without getting the above error. So you must have done something different than I did. Perhaps there was an error before, and this is some follow up error?
Can you reproduce that?

We reproduced it on 4 PCs in the office. I get this error after I clicked to the button. But I can clear today's history, just cant delete the old ones.

When I arrived home I will try on my home pc.

Same here: can't reproduce.

Instead of that, I found two possible bugs related to Query History tree: #170 and #171.

170 It's very similar to my problem

Tested my home pc, and same issue:

But after this I can clear history.

170 is the same issue, going to close that one.

Sorry, closed by mistake

Finally I could reproduce it, for some reason. The confirmation dialog was resetting the settings path to the history, so the "delete path" method made an emergency stop with a crash (which is better than deleting the root key for all settings). Fix was to set it again after that message dialog.
