In general the most useful pieces of information are ... complete terminal output, $PWD and the command used to start an application. Also the exact Wine version $(wine --version), and where did it came from (self-compiled or binary). All of them are absent from the report.
That's one report generated by apport, which is, as you and others were writing, totally useless (that was my first impression, too)
So, I'll go back to normal business for bugreporting and pointing the users to winedbg.
Again, if you can get it to run the backtrace with "wine-pthread" as binary, it will likely be better.
(gdb wine-pthread, attach pid, bt ... does show more)
I have however no clue how apport works and if this can be done there.
