Comment 18 for bug 252174

There is no need for extra comments reporting the problem as this is a known issue. The next step is to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report.

I'm just a novice at this, but it looks like Luca's stacktrace is missing debug symbols (eg. libdbus-1-3-dbgsym). Has anyone found a reproducible action that causes the crash?
