I'm having some problems lately with sensors returning what appears to be fairly random results.

Example:
A simple llSensor("", NULL_KEY, ACTIVE, 96.0, PI) on a 2 second timer at my current position right now returns
"Event Monitor v0.2 - SMM 0.2" (scripted object with a listener, so correct).
"SMM-Deepsea pod" (unscripted, non-physical, non-phantom, non-flex, static build, so incorrect).
Some plants and various other unscripted, non-physical objects show up too.
Also noticed that several poseball scripts in various places now show as being active where they used to always show as idle in the past.

Seems like something that could have fairly major consequences for many existing scripts and it also makes it hard to check if your scripts go idle like they should.

I can't see anything in the JIRA about this, there are no comments about changed behaviour in the LSL wiki and I don't get any responses in other forums either, but I still have some doubt that I'm merely hallucinating... If anybody is seeing the same, I'd like to hear about it.

(Note: the results are the same whether I use my own scanner scripts, Conover's Advanced Object Scanner, scan-foo or other scanners, so it can't just be due to me screwing something up. I think. The problem also occurs in different sims).
