Yes probably.

 From the build directory (tip: you can run LyX from there without 
installing):
1/ make sure that you have pulled the latest changes from git and built them
2/ run "gdb src/lyx"
3/ when you see the "(gdb)" prompt, type the following commands
catch throw
run
[do the crashing thing]
bt
4/ send the output of the bt command

f you have issues with thunderbird, try to close it before debugging.

Indeed. But encouraging users to use latest version is good.

But I am not sure that this particular instance is encouraging :)

These are on by default with development builds.
