Description Jung-uk Kim freebsd_committer freebsd_triage 2016-07-15 06:49:04 UTC 
I have a serious regression with ko_KR.UTF-8 locale after r302324.  MATE is unusable because mate-panel is busy looping and eating 100% CPU.  GNOME 3 does not start at all, i.e., nothing but mouse cursor on black screen.  After reverting the commit, everything is back to normal.
Comment 1 Baptiste Daroussin freebsd_committer freebsd_triage 2016-07-15 09:22:31 UTC 
A simple ls will do it as well.

Can you confirm that this is the same regression as for zh_CN.UTF-8 aka reproducible with:

touch "<ACJKCHARACTER>1"
touch "<ACJKCHARACTER>2"
ls

Than ls will eat 100% CPU?

Yes, "touch 예1 예2 && ls" shows the same symptom.
Comment 3 Jung-uk Kim freebsd_committer freebsd_triage 2016-07-15 18:20:49 UTC 
Note this problem is not just for CJK locales.  "touch Æon1 Æon2 && ls" with en_US.UTF-8 locale shows exactly same symptom.

Both GNOME 3 and MATE are working as advertised.  Thanks!
