this is what I got from my JIT debugger.
Those don't look like valid offsets into the .dll file. Do you have any info on the offsets themselves, or info on where the files were loaded in memory so that I could get a proper offset? Without that I won't be able to trace this.

here's what event viewer had.
Ah, excellent. Thank you. I'll take a look into this. I suspect that whatever this issue is, 1306 didn't fix it.
Well, shoot. The call traces to a destructor for one of the icon structs, which means somewhere some memory got messed up. As best I can tell from your stack trace (that was helpful in getting me a little further), this happened somewhere in the dynamic icon code. Unfortunately I don't have more answers than that.
