The backtrace is unfortunately completely mangled and of no use. Can you reproduce this problem, and if so how ?

I'm not sure; yesterday morning it happened 4-5 times in succession (I'd open libreoffice, recover the files that were not closed properly due to the previous crash, edit them, try to save, and *crash*).  By the time I'd gotten the bug reports submitted, the problem no longer occurred (and hasn't occurred since).

https://retrace.fedoraproject.org/faf/reports/371375/ points here but has a different backrace in it. That one suggests a crash in the rtf export (which is related to copy and paste as well)

Committed http://cgit.freedesktop.org/libreoffice/core/commit/?id=7d53f81f0a88afcff0f60bbd066a5645ac2e6a8b upstream which might help. Without a reproducer I'll close this as closed->upstream

This happened again just now: multiple times trying to edit an RTF, ctrl+s caused the program to crash.  I finally was able to save by going to "file -> save", and after that, had no problem with ctrl + s.

Unfortunately, the automatic bug reporter won't gather any new data since the bug has already been reported.
