CodeAi (https://github.com/C0deAi), an automated repair tool developed at QbitLogic (www.qbitlogic.com), suggested the following fix. Could I submit it as a patch if it looks alright?

plugins/saveactions.c: “doc->file_type” pointer might be dereferenced when null on line 283.  Initialization may be provided by “doc” passed in as a function argument, but a null check would be prudent just in case. The fix checks “doc->file_type” for null before allowing a dereference on the following line.  A snapshot of the bug report generated by CodeAi is attached.  A full report is available upon request.
