Hello,
I only like to inform that I was able to fix that bug. It was for sure
an bug in my application. But from this backtrace I wasn't able to find
it. While hinting another bug I got a backtrace in my dispatcher and
found out that I do some Evas object stuff in the wrong thread. I
simply moved this code after dispatching in my ecore thread and it
works now great without any crashes. :-)
