Anyone ever seen crashes like this before?

These (just these 3) have been reported by customers over the last month or so. We have only seen them on Snow Leopard, but we hardly have a statistical sample. I have never seen it during development or testing. It seems to be connected with disposal of a QLPreviewView by NSOpenPanel when it is closed. Note that it's not the main thread that crashes, but it looks like it's doing something that whipped the rug out from under the thread that did. Note also that in all cases the faulting address appears to be part of an ASCII string (and not one I recognise).
I have raised a bug report about this (7826287) but I thought I'd see if anybody here has seen something similar. I don't think it's us. I like to think that we see these weird, rare crashes because of the reporting facility (based on Uli Kusterer's UKCrashReporter) built into our software, rather than the fact that we have lots of bugs in our own code. AFAIK, we are good citizens when it comes to respecting other people's memory, but you can never be 100% sure.
