Redmine

I'm seeing an issue when where issues which are visible and readable to all start returning error 404 not found when ALL of these conditions are met:

• user has diacritics in his name "Veřmiřovský", but it seems that I can trigger this by any name which contains "ř" ("r" with Czech accent)
• user is expanded in an issue comment from the from of Scott Posch . Interesting that pressing "preview" shows the comment correctly, but hitting "save" shows a green message that save was successful. But the bug is not visible (404 not found). If I go into the DB (journals, find the comment, change the text to some other existing user or remove it), bug is again visibile.
• user selects that he wants to be notified for all events on all his projects. Switching the notification "owner of issues only" or "no events" makes this go away

Turning off e-mail notifications has no effect, I also tried sendmail delivery and SMTP with TLS. Still the same.

I tried creating a new, fresh account - didn't help.

production.log snipped with logging level turned to debug (look for "Missing template, responding with 404" which seems to be the issue).
