Description Joachim Geiler 2006-06-17 13:48:05 UTC
Version:           1.6.3 (using KDE KDE 3.5.3)
Installed from:    Ubuntu Packages
OS:                AIX

On programs with lots of output sometimes characters are lost. I can reproduce this behaviour with the command hexdump, where output sometimes looks like:

0003560 000d 0000 0000 0000 0000 81ed 0000 0000
0003570 6966 746c 7265 5455 0005 0e03 925a 5544
0003580 0078 5000 014b 1702 14 d049 4834 3d77 f021 0001 b400 0003 0800
00035a0 0d00 0000 0000 0100 0000 a400 b981 001c
00035b0 6600 6c69 6574 2e72 5563 0554 0300 5a0b

The problem exists only with konsole, but not with xterm, xfce-terminal, gnome-terminal or linux-textmode-konsole.

My System ist a K8 with dual core, running Ubuntu 6.06  
kernel 2.6.15-25-k7 #1 SMP PREEMPT Wed Jun 14 11:43:20 UTC 2006 i686 GNU/Linux

On my laptop runs the same Ubuntu linux with (nearly) the same kernel (2.6.15-25-386), the same KDE 3.5.3 and konsole 1.6.3 without any problems. The only difference I see is that it has only a single CPU.

Do you have a screenshot showing the appearance of konsole when characters are lost?
Comment 2 Thiago Macieira 2006-06-26 09:27:46 UTC
I cannot reproduce this problem with Konsole and hexdump.
Comment 3 Lars Doelle 2006-06-26 16:33:48 UTC
Joachim,

you are not perhaps running "mc"? mc is known to have a bug in the subshell
pipeline since ever causing drops to occur pretty reliably on longer printouts.

If so, you might not have recognised the problem with other terminals, since
you did not start mc in them before your test.

Lars,
thank You very much for Your comment. You are right. I didn't know about the mc bug. I am sorry for the bug report, the problem is not konsole, the problem is mc (and a little bit me :-( ).

Can You please close the Bug

Joachim

Not a bug in konsole, it seems.
