It's nice to finally see what looks like a reasonable backtrace.  To get 
more information about frames 0--3, you'll need to install some more 
debuginfo packages:  at-spi2-atk-debuginfo, at-spi2-core-debuginfo, and 
dbus-debuginfo.  I don't know if it's possible at this point to get gdb 
to read the debug information for cygdbus-1-3.dll and cygatspi-0.dll 
(once you install the debuginfo packages) or if you have to wait for the 
next crash.  I'm sure Eli knows.
