This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

When trying to refile an Org todo task, I crashed Emacs. My full init
file was loaded, I have no way to reproduce this or give a recipe, so I
send this backtrace just FYI, maybe its helpful:

Please use the procedure described in the node "Crashing" in the Emacs
User manual to produce file names, function names, and line numbers
from these addresses; then post the results here.  Otherwise, these
addresses are impossible to interpret on any other machine but yours.

Thanks.

ok, didn't know that ... I post the result, but it doesn't look very i
nformative either:

Are you sure this is the same binary that crashed?  Did you rebuild
Emacs in the meantime?

I'm pretty sure I have only one Emacs on my machine, and did not rebuild
anything. '/bin/emacs' was a symlink, but using the real thing
'/usr/bin/emacs-24.3' did not change the output.

Maybe your binary is stripped, then.

Stripped? What do you mean with that? It works, at least, I'm using it
right now.

Stripped of all symbols.

Yes, stripped binaries work just fine.

Anyway, since the crash is not reproducible and the backtrace sheds no
light, nothing can be done; hence closing this report.
