Description Tobias Koenig 2010-02-14 11:59:51 UTC 
Version:            (using Devel)
Compiler:          gcc 
OS:                Linux
Installed from:    Compiled sources

Steps to reproduce:
In current SVN trunk version open KAddressBook
  - select a contact
  - choose File -> Export VCard 3.0
  - choose 'Selected contacts' -> Ok
  - click Ok again
  - choose a filename that does not already exists
  - click Ok again
after exporting the contact, KAddressBook crashes with the following bt:
Application: KAddressBook (kaddressbook), signal: Segmentation fault
The current source language is "auto; currently c".

The crash doesn't happen if you choose a filename that already exists, in this case a 'Are your sure to overwrite' dialog is presented and KAddressBook doesn't crash.

My guess is that the KIO::NetAccess::upload() in VCardXXPort::doExport() might have some influence, however it worked before, so it must be a change somewhere down in KIO or KDirWatch
Comment 1 Maciej Mrozowski 2010-02-15 03:42:25 UTC 
I confirm the exact same bug that crashed Dolphin for me.

Happened after I navigated to some directory and created new folder using dolphin in there.
My kdelibs is built with inotify support and I guess it's what triggered this crash within kdelibs code just after new directory (successfully created) appeared.

This is KDE 4.4 (4.4 branch), Qt4 4.6.1

Comment 2 Tobias Koenig 2010-02-15 09:12:09 UTC 
Hej again,

I came accross this crash on other locations as well.
Mostly when closing a KFileDialog somewhere.

Ciao,
Tobias
Comment 3 Dario Andres 2010-02-15 15:10:16 UTC 
From bug 226608:
-- Information about the crash:
I added an iCal file based resource using the Akondai KCM (and gave it a
filename that did not exist in a folder that did exist) and got the following
crash report.

The other resources I have are Local Folders (offline) and Personal Contacts
(has a green dot, but no status message, and I've just imported a bunch of
contacts from a VCF file successfully).  The KCM also has a green dot (and no
status message) for the iCal resource.  The iCal file seems to have been
created successfully.

From bug 227004:
-- Information about the crash:
The attachment is a .txt file. I click on it, select the place where to save it
and click the save button and then Kontact crashes. The attachment is correctly
saved to disk though.

The crash can be reproduced every time.
