Not recently. The problem is that the debian/sid Evolution package
doesn't have debug syms, so the backtraces aren't very useful. I
submitted a couple of those into bugzilla earlier and they gor rejected
out of hand.

Compiling for debug takes forever on my machine and I didn't bother to
do that last time when evolution got pulled from the debian repository.
Last time (couple of months ago with evo-1.2.1 I think) I had a real go
at tracking down the crashes I ended up with this:

"I had another crash in a completely different place (syncing the index
file of my Sent folder to disk). One pointer on the block list had a
next pointer with the value 0x200. And here we had a pointer with the
value 0x100. Looks very suspicious to me. I don't suppose these numbers
mean anything to you? Could be a flags field, of some sort, I guess."

So, I was seeing similarily garbled pointers in different lists and
crashes in places that traversed those lists. Unfortunately, the above
didn't elicit any comments on the mailing list and I don't know enough
about the code to track down the cause. If you want to give me a hand
I'll give it another go. Recompiling now.

Cheers,
