From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040627 Description of problem: If I create a directory with newline (yes, quite unusual) inside, enter this directory and then start mc, that's the last thing I can do, it hangs and only kill <mc_pid> helps. Version-Release number of selected component (if applicable): mc-4.6.0-15 How reproducible: Always Steps to Reproduce: 1. A=$(echo -ne 'newline\ndir') 2. mkdir "$A" 3. cd "$A" 4. mc 5. press <TAB> Actual Results: mc hangs there when you try to change the dir or switcg the panels. Expected Results: Such directory should be displayed like in ls ('?' instead new line or whatever), but not hang mc. Additional info: I've tested this with RH9, FC1 (text and graphical console) and FC2 with UTF-8 and without. Even the Leonard den Ottolander's patched version (mc-4.6.0-14.10n) nothing changes for me. If I run mc with ltrace: 'ltrace mc 2> ZZZ' it seems to work (slow, verry slow but works), but with 'strace mc 2> ZZZ' it hangs again and in the log there's probably something usefull I did not find. When used without concurrent shell (mc -u) everything works fine (but the newline character is simply ignored when showing the path). I suspect there can be other weird characters that can hang or even crash mc, but I have not tested this yet.
This is now fixed in rawhide. Jindrich

The patch is not good enough. It causes MC to hang when the subshell is tcsh, as can be seen from this strace: 9770 pts/0 S+ 0:00 /home/ptsekov/mc-test/usr/bin/mc -U 9773 pts/5 Ts+ 0:00 -csh [ptsekov@baba-meca abcdef]$ strace -p 9770 Process 9770 attached - interrupt to quit read(6, See also the lsof output.
Which patch would this be again?
This is the "uglydir" patch you can see in our src.rpm.
