(I'm on Linux 64-bit. This happens with current Git master as well as
the 4.8.4 release. 4.8.3 does not have the issue. I could not bisect
the commit causing this because somewhere along the way, viewing HTML
files is not possible at all.)
When viewing HTML files with "mc -v" (or "mcview"), a segfault occurs.
Call stack:
name_quote (lib/util.c:256)
expand_format (src/filemanager/usermenu.c:863)
regex_command (src/filemanager/ext.c:177)
view_file_at_line (src/filemanager/cmd.c:647)
do_nc (src/filemanager/midnight.c:1006)
main (src/main.c:567)
In name_quote(), 's' is NULL and thus a segfault occurs when
dereferencing it. Quick fix below. The proper fix is probably to avoid
the whole thing in expand_format().
