Description Oliver Zimmermann 2007-07-24 18:17:46 UTC
Version:           Unbekannt (using KDE 3.5.7 "release 60.1" , openSUSE )
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release

After the latest update via YaST (SuSE 10.1) Kontact crashes often. Sometimes at startup, sometimes just when changing the application (going from Mail to Calender, etc.) A backtrace is:

Using host libthread_db library "/lib/libthread_db.so.1".

Comment 4 Dirk Meetschen 2007-08-03 14:02:54 UTC
It's a problem in libkcal obviously. For me it even makes the standalone korganizer crash. I can reproduce it by deactivating and reactivating the active resource in the resource view (in both kontact and korganizer). But it also makes kontact crash, when opening the overview.
Comment 5 Bram Schoenmakers 2007-08-04 13:43:06 UTC
We need a better backtrace in order to track it down. Also attaching the affected ICS file here would be nice.

Please read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports for the backtrace part.
Comment 6 Oliver Zimmermann 2007-08-04 16:03:34 UTC
There is no debug-rpm available for kdepim  resp. kontact. What is an 
Comment 7 Bram Schoenmakers 2007-08-05 11:00:12 UTC
An ICS file is where the calendar data is stored into. When your calendar is stored locally, you usually find it in ~/.kde/share/apps/korganizer .

That you can't find the debug packages looks like a openSUSE issue I can't help you with, unfortunately.
Comment 8 Oliver Zimmermann 2007-08-05 11:53:21 UTC
Im am getting the current KDE updates from


Post an ICS-files would mean posting my calender with entries?
Comment 9 Bram Schoenmakers 2007-08-05 12:10:48 UTC
I can understand your ICS may contain private information, and of course I won't force you to publish all that.

You can mail it privately to me if you don't have problems with that.

Or if you don't want to, you can try to locate the problem yourself. Copy your ICS file and try to track down which entry inside triggers the crash. To quickly accomplish this, use the binary search method:

Strip the first 50% of the entries in the copied file and load that file in KOrganizer. If it does not crash, the problem was in the first 50%, else it's in the remaining 50%. Repeat these steps until you have only 1 item left. You can eventually replace private texts with some other texts (and test after that if the crash still occurs).
Comment 10 Dirk Meetschen 2007-08-06 10:14:07 UTC
I've tried to locate the entry as you told. But it seems like it is the mere amount of entries causing the crash, for me it's 64 VTODOs, 103 VEVENTs, and 51 VJOURNALs. I took a copy of this file, deleted the first half of it and tried to produce that crash, but everything was stable, then. The same with the second half. Feeding in the whole amount again korganizer crashes when loading the file for the second time.
You will understand, that I can't replace all potentially private text by hand.
If you can provide a debug RPM for openSuse 10.2 (I use kdepim3-3.5.7-37.1@i586.rpm), that might be very helpful.
Comment 11 Bram Schoenmakers 2007-08-06 21:07:14 UTC
Maybe the openSUSE forum can help you with that, because my knowledge about openSUSE is lacking.
Comment 12 Oliver Zimmermann 2007-08-06 23:13:31 UTC
If it is the amount of entries, it's bad. I like to keep old entries in order 
to have a research possibility of where I had business meetings with whom. If 
I would not like to delete those.

But the single components of Kontact (Kmail, Korganizer, etc.) work fine if 
started solitary.
Comment 13 Andre Woebbeking 2007-09-07 16:14:49 UTC
Hi, I've the same crash with self compiled KDE 3.5.x branch (some weeks old). As my backtrace is a bit more verbose it's maybe helpful:

Comment 15 Hugo Costelha 2007-09-11 11:20:17 UTC
What seems strange. is why it happens when starting kontact, but not when starting korganizer, since calendar is a korganizers's thing, right?
Comment 16 Oliver Zimmermann 2007-09-11 11:57:23 UTC
Yes, each applikation works fine if launched independently. There must be a flaw in the way how they are implemented into Kontact.
Comment 17 Christo 2007-09-11 12:24:57 UTC
i disabled the summary-module and :-( dont use it anymore .. since it reproduceable crashes Kontact ... i also think that its ical-based albeit Kalendar has no issues .. :-) 
Comment 18 Hugo Costelha 2007-09-13 13:54:15 UTC
I installed the debuginfo package, and now it does not crash!!!!

Let us hope it crashes soon, so that I can paste here the complete crash log.

Kontact crash backtrace log

It crashed again. Here goes the backtrace log with debug information.
Comment 20 Hugo Costelha 2007-09-18 11:10:11 UTC
I found out that it only happens if kontact is started in the summary module. If I do "kontact --module kmail", it starts without crashing. However, if click on the Summary view, it crashes right away. Clicking on calendar does not give any problems.

So definitely, the problem is all within the Summary module.
Comment 21 Oliver Zimmermann 2007-09-18 17:38:12 UTC
It's not that easy: I start Kontact always with the summary, but the crashes 
occur very irregularly. If that happened here (most often several times in a 
row), I started KOrganizer separately, disabled the standard ressource (the 
only one apart from birthdays from KAddressBook). Then Kontact starts, I call 
the calender and reactivate the ressource.
