GNOME Bugzilla – Bug 136530
The calendar window shows invalid appointment dates
Last modified: 2004-12-22 21:47:04 UTC
Dates are bolded where events/appointments/tasks are non-existent. See the attached screen capture.
Created attachment 25329 [details] Date bolded on the 16th of the month on which no appointment/task has been set.
I think it's a dup. You can try the patch attached to bug #134931 and see if it fixes the bug. *** This bug has been marked as a duplicate of 134931 ***
