TApplication.HandleException Access violation

[traumschule]

Just hit the first crash with tomboy-ng in the background, without really working with it. Will see if it is reproducible.

edit: oh and i found a note is missing, maybe it crashed trying to save it.

This looks, to me, as if "something" happened, that particular note decided it needed to be saved and we ran into the same problem that caused the exception in #14. Thats won't happen again but what was the "something" that caused the shutdown in the first place ?

Its particularly disturbing in that it lost a note. I was pretty sure thats not likely to happen anymore. One thing, I thought at one time I saw a note being saved on exit that had not been changed. Did not chase that up at the time, it could be related but is not the "something" that triggered off the problem. Interesting that you were not interacting with tomboy-ng at the time, once changed notes are saved, it really should be doing nothing .....

If you see it happen again, be interesting to dee what dmsg says, OOM killer is a (remote) possibility.

Thanks for the explanation. I close it as unreproducible and possible duplicate of #14.
