Description Peter Baumann 2005-08-09 10:19:50 UTC

Version:           1.5.2 (using KDE KDE 3.4.2)
Installed from:    Fedora RPMs

I have read bug #85779 but I still have exactly the same problem.
I'm using this function "Save History as..." very often and get a lot of crashes (9 times out of 10).
I just login to another system with ssh and display a lot of lines tech-informations which I want to save with the "Save History as..." Function.
This still doesn't work.
I have a standard FC4 installation with a NVIDIA Graphic Card.
Here's the Backtrace:

Any Idea what the problem could be?

Comment 1 Kurt Hindenburg 2005-09-18 07:28:41 UTC

This is likely the same as 84403.  Too much data, not enough RAM.

With KDE 3.5, I saved a 350,000 line History, it froze Konsole for about 1:45 mins and used 100% of the CPU but it didn't crash (750MB RAM).

I cat this file 5 times...
% wc -l /mnt/part5/usr/share/dict/extra.words

It would be helpful to know the size of the data you were trying to save.

It may just be that people are going to have to stop using unlimited history.

Comment 2 Robert Knight 2006-08-04 20:04:08 UTC

Rewrote lots of the code related to this recently, so it is quite likely that the problem will have disappeared.  

Please reopen if the problem still occurs with the Konsole for KDE 4.0 betas (when they eventually arrive).
