Comment 1 Jan 2011-05-01 22:56:53 UTC 
can't reproduce this bug. Every year i tested was working well, but i didn't checked if the displayed day of the week was correct, as i tried 1402, 1, 5556 as well.
Comment 2 Stefan Borggraefe 2011-05-02 01:13:09 UTC 
@Jan: Which KDE, Qt versions did you use? Which distribution?

Git commit 33fa0c965013d7abaa39cc17aa69fa2b18eefda3 by Aaron Seigo.
Committed on 02/05/2011 at 14:54.
Pushed by aseigo into branch 'KDE/4.6'.

prevent crash when hiding the year boxes more than once

BUG:272077

QSpinBox emits the finished signal when enter is pressed and when
it loses focus. so if you hide it on enter, it then loses focus
and the signal is emitted again. even if the value hasn't changed
and no editing was done (not even returned from the previous signal
emission). moderately lame.

plasma-desktop (0.4) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

(Actually I'm not able to say for sure that this bug and the one I'm reporting are identical but I'm guessing that they're the same and hope that the attached crash info might be useful.)

Tried to change the date in the calendar as per the original bug report. 

Note also that the desktop froze for a while before crashing. When the desktop started working again the calendar year had changed to -1. When I typed 2011 and pressed enter the desktop crashed.

Thanks again!

In which KDE version has been the bug fixed? I can still reproduce using 4.6.3.
Comment 12 Aric Warsaw 2011-06-12 20:17:36 UTC 
KDE maintenance release 4.6.4 fixes this bug.  After application, I've
tested and confirmed.  Thank you.
