Description Diego Iastrubni 2004-08-18 16:24:44 UTC

Version:            (using KDE KDE 3.3.0)
Installed from:    Compiled From Sources

I took a pot file from kdeartwork and copied it into the corresponding language. Then I clicked on the file in konqui. 

It always (tried with different files) when I tried to translated messages as this one:
<center><b>RiscOS preview</b></center> 

(translating "preview").

Typing latin letters there did not affect, and the application works. I attach here the trace from drkonqui, but it will not be helpfull.

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

Comment 1 Rogério Pereira Araújo 2004-08-18 21:51:34 UTC

I got a crash in kbabel when i start to typing some words translated to brazilian portuguese, kbabel just crashes and prints a very large stack trace. My KDE version is 3.3 rc2 compiled with gcc 3.4.1

Comment 2 Igal 2004-08-18 22:08:55 UTC

Another crash while typing hebrew here. When I type English on the same strings - nothing happens. 
KDE version 3.3_rc2
KBABEL compiled from source on Gentoo by GCC 3.3.4

Comment 3 Munzir Taha 2004-08-18 23:45:55 UTC

It happen a lot of time for me when typing Arabic also. The problem is it's very difficult for me to always reproduce it in a systematic manner. Sometimes, it happens, sometimes it's not! It's really a very annoying problem.

Comment 4 Stanislav Visnovsky 2004-08-19 10:24:09 UTC

Anybody with a backtrace including the debug symbols?

Also, I need your qt version.

Comment 5 Stanislav Visnovsky 2004-08-19 10:31:13 UTC

Also, do you have spellcheck on the fly enabled?

Comment 6 Mashrab Kuvatov 2004-08-19 13:14:52 UTC

I had the same problem with the yesterday's KDE_3_3_BRANCH + QT-3.3. Disabling "spellcheck on the fly" solves it.

Comment 7 Igal 2004-08-19 20:12:24 UTC

I have QT 3.3.3
Disabling "spellcheck on the fly" do solve the problem.

Comment 8 Stanislav Visnovsky 2004-08-24 15:32:52 UTC

Created attachment 7250 [details]
Delete highlighter for deleted text editor

Could anyone, please, test this patch? The behavior improves
for me (even with on-the-fly-spellcheck enabled).

Comment 9 Munzir Taha 2004-08-24 20:26:33 UTC

cuco?

Comment 10 Andrey Cherepanov 2004-08-25 16:30:48 UTC

I test your patch. After applying work normal, without crash. Thank you very match!

If you patch file in CVS you can close this bug. ;)
