Bug 184151

Version:            (using KDE 4.2.0)
OS:                Linux
Installed from:    SuSE RPMs

Sometimes kontact crashes when selecting a mail folder inside kmail.

Normally i start kontact by klicking on its icon in the taskbar.

Currently it seems to happen with every folder.

Here is the backtrace:

Starting it from konsole results in the following output; but now it does not crash (probably no depencies):

Calling appendChild() on a null node does nothing.

Then I click on multiple folders without being able to reproduce crashing. Inside one folder I select all mails and press <Shift>-<Del> to delete them (really delete them; not move them to trash folder). The I get the following output:

kontact(13307)/kmail KMail::MessageListView::StorageModel::releaseMessage: Trying to release a message at row  10  that no longer exists in the folder

Here is the output of 'rpm -qif /usr/bin/kontact':
