mmh hard to descide what happens here.
We trigger a deleteMessage for an item. This results in a signal and the only one who is connected to the signal is kmail
kmail/kmreaderwin.cpp
void KMReaderWin::slotDeleteMessage(const Akonadi::Item& item)
{
if ( !item.isValid() )
return;
KMTrashMsgCommand *command = new KMTrashMsgCommand( MailCommon::Util::parentCollectionFromItem(item), item, -1 );
command->start();
}we recently changed the code here to fetch the full item if it is not populated:
066b3d91e37aa0795ff74e39594969a360dff784
Does he checks with kdepim >= 4.13.0.17?

ok 4.13.0.17 should be used already.
the stacktrace looks strange. Because messageviewer_bodypartformatter_text_calendar.so only triggers deleteMessage, when the user interacts with the interface and the user accepts/decline/doanything with an invitation. I don't see anything, that is triggerd by destructor.
Installed debug symbols can help here to unterstand what excatly triggers the deleteMessage in first place.

Judging from the backtrace it could be that we have calls to exec that execute the eventloop:
#48 0x00007f8b1d1b23a5 in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from
which could lead to reentrancy issues.
