Not yet. I'm not entirely sure what information would be required to help them debug it. I have a dirty great session log from the upgrade, but no real confidence that it's usable in its current form and doesn't contain anything private.

If aptitude were to produce a nice goal-seeking log ("I uninstalled this package because it conflicted with that one, which in turn I was installing in response to this, which occurred in furtherance of the following goal which was a direct dependency of the thing you specified on the command line") then I could just send the specific reason it uninstalled itself. It may be possible to extract something resembling this information from the session log, but I haven't tried yet.
