           Summary: Closing event database causes many warnings and memory
                    corruption
           Product: libeventdb
           Version: 0.30
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: default
        AssignedTo: gpe-bugs at linuxtogo.org
        ReportedBy: g+gpe at cobb.uk.net
   Estimated Hours: 0.0


If a program gets a collection of events using event_db_list_for_period, then
unref's the events and closes the event database, a large number of the
following warning messages are displayed:

GLIB WARNING ** GLib-GObject - IA__g_object_remove_toggle_ref: couldn't find
toggle ref 0xa7f2e3e0(0x8050800)

(By the way, each warning reports the same addresses.)

On some occasions this is followed by a core dump:

*** glibc detected *** malloc(): memory corruption: 0x080506e0 ***

The attached program reproduces the problem (as long as there are some events
already in the database).

Events with recurrence rules containing WKST= clauses cannot be imported into
gpesyncd (or gpe-calendar).

This is a bug in libmimedir (mimedir-recurrence).

mimedir_vcal_get_event_list and mimedir_vcal_get_todo_list do not increment the
reference counts on the components they return.  This causes crashes if the
caller unref's them.

The workround is for the caller not to unref them, of course.

The is a libmimedir bug.

           Summary: Alarm triggers are not exported

When exporting events with alarms, the trigger value is not included.  So, when
the event is synchronised with an external system the alarm is likely to be
lost.

This is a bug in libmimedir.  The "target" property of MIMEDirVAlarm is not
writable.  A patch is attached.  With this patch applied to libmimedir triggers
are exported correctly.

Imported events do not include any alarms.

This is a restriction in libmimedir (with a FIXME comment!). 
mimedir_vcomponent_read_from_profile does not handle parsing of the VALARM
subcomponent.

I have no patch for this at the moment.
