I'm using Evolution 2.5.92. 
somehow evolution stopped reminding me of my appointments. this is what I have from .xsessions-erros:

********************************
evolution-alarm-notify-Message: Setting timeout for 26880 1141858800 1141831920

evolution-alarm-notify-Message: Adding file:///home/koto/.evolution/memos/local/system
evolution-alarm-notify-Message: Loading alarms for today
********************************

the calendar is there but no alarm pop ups are being generated.


this is what evolution says if I create a new appointment:

********************************
(evolution:27274): GLib-GObject-WARNING **: IA__g_object_set_valist: property `width' of object class `GtkTreeViewColumn' is not writable
(evolution:27274): libglade-WARNING **: unknown property `ellipsize' for class `GtkImage'

(evolution:27274): libglade-WARNING **: unknown property `width_chars' for class `GtkImage'

(evolution:27274): libglade-WARNING **: unknown property `single_line_mode' for class `GtkImage'

(evolution:27274): libglade-WARNING **: unknown property `angle' for class `GtkImage'
********************************


something else which is very strange: suppose its 1600 and I create an appointment for 1610. I click the alarm button and choose the customize option. the custom alarm will now read: pop up an alert -1 minutes before the start of the appointment. if I edit the alarm then the minutes field actually reads this big number: 4294967295. so there seems to be an overflow somewhere to me.

I don't know if these are two different issues but I just thought about posting as much info as possible
