Comment 1 Stefan Borggraefe 2006-07-18 02:31:39 UTC

I'm using the current Debian Sid packages of KDE 3.5.3/Kontact 1.2.3.

Here's a backtrace with line numbers. I can reproduce the crash with the same steps given in bug 131004, but with an older account which already has more feeds and lots of contacts contacts. Kontact crashes every time.

Steps to reproduce:
1. Start Kontact. 
2. Click on the "Feeds" icon. 
3. Click on the "Contacts" icon.
4. Select "File|Quit".

So this is similar to bug 131004, but the backtraces looks slightly different. Thus I'm confirming this bug for now, too. Lets see whether they are dupes later.

Comment 3 Tobias Koenig 2007-02-12 16:01:51 UTC

Hi,

the KIO::NetAccess call in KABC::ResourceFile::save was removed for 3.5.6, so the crash
shouldn't happen there again. For the KABC::ResourceLDAPKIO we can't change it before KDE 4.0, sorry :}

Ciao,
Tobias
