Yeah, Patrik mailed me about it too, I just didn't have the time earlier. John Seymour's comment in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=726600#75 seems helpful: [Tue Oct 22 11:56:15 2013] -e: Strings with code points over 0xFF may not be mapped into in-memory file handles [Tue Oct 22 11:56:15.193665 2013] [:error] [pid 8510] [Tue Oct 22 11:56:15 2013] -e: open body: Invalid argument at /usr/share/perl5/MIME/Entity.pm line 1878.\n A similar failure can be triggered with something like this: perl -CO -Mstrict -we 'my $a = "\x{2660}"; open(my $h, ">>", \$a) or die "open failed: $!"; print $h "test\n"; close $h; print $a' which dies with 5.18 but not with 5.14. This is by design: the relevant perl5180delta entry is PerlIO::scalar has been upgraded to 0.16. The buffer scalar supplied may now only contain code pounts 0xFF or lower. [perl #109828] and the change is http://perl5.git.perl.org/perl.git/commit/02c3c86bb8fe791df9608437f0844f9a8017e3b6 which was thoroughly discussed in the aforementioned ticket https://rt.perl.org/Public/Bug/Display.html?id=109828 So the reproducing recipe presumably involves non-ASCII, non-latin1 characters in the ticket. Hope that helps a bit. Not sure if this is a bug in MIME-Tools. My half hearted attempts to trigger it by parsing a crafted UTF-8 email message weren't successful (meaning MIME-Tools was behaving more or less correctly.) So it needs something more complex to show up. I see OTRS, Kernel/System/Encode.pm in particular, is using the Encode internal functions _utf8_on() and _utf8_off() quite a bit. The root problem might be somewhere there. I can look at it more (time permitting) if somebody finds a way to reproduce it. -- Niko Tyni nt...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
