Comment 4 for bug 2028912

I somehow managed to fix the issue, and the attached patch can fix the issue. However, there seems to be no git tree exist for mtools, so SRU could be tricky

I wrote an email to Chris Lamb, who is the maintainer of the mtools debian package, and unfortunately he said that he will orphan the package(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1042948). The maintainer also mentioned that he updated the mtools code on gitlab(https://salsa.debian.org/lamby/pkg-mtools) to the latest version(4.0.43) from upstream, not sure if it means that there will be a 4.0.43 debian package released recently
