[Kde-pim] KMail opening by message serial number abaility

[Mathieu Dupuy]

Hello Everyone.
I'm working with Trueg on adding Nepomuk features into some parts of 
KDE. One of this feature
It's mostly a proof of concept, and something else cleaner and more 
powerful will be done once akonadi will be ready, but for now we need it 
to work with KMail.

What I need is kmail messages uniques Id which I can retrieve from 
message and especially with which I can open kmail with. For retrieving, 
I use KMMsgBase::getMsgSerNum(), no problem on this this side.
For opening KMail with the serial Number as argument, I hade to patch 
KMail following McGuire intructions, and following the --view option 
implementation.  It works well, but It crashes when closing the kmail 
mail window .Tom has no idea of what could cause it, I searched a lot, 
and I cannot understand why it crashes ; so here am I soliciting kde-pim 
mailing-list help.

Here is join my patch ; I had an  --viewid (yes id is not well choosen 
but it's shorter than --viewByMsgSerNum) option following the --view one 
; the code is short & simple.

Tom suggests that it crashes because kmfolder remain open ; but I can't 
close it currently (I made a slot for closing it on KMReaderWindow 
deletion, but it crashes before the slot could be called)

Here is a crash gdb core dump :
