Description Oliver Putz 2008-06-23 19:27:51 UTC 
Version:           4.00.82 (KDE 4.0.82 >= 20080610) "release 3.5" (using 4.00.82 (KDE 4.0.82 >= 20080610) "release 3.5", compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.5-1.1-default

I tried to reproduce bug #157737. Therefore I opened a textfile on sftp://localhost via konqueror in kwrite. While the file was still loading, I typed some text into the file (and tried to save it). The result was the following crash:

Application: KWrite (kwrite), signal SIGSEGV

Comment 1 auxsvr 2008-11-21 22:48:44 UTC 
This just occurred here, in KDE 4.1.3.
Comment 2 Dominik Haumann 2009-06-04 18:15:36 UTC 
Can you please test again with KDE4.2 or even better upcoming KDE 4.3 / trunk?
There were quite some fixes with regard to the layout cache. So maybe it's fixed...
Comment 3 Milian Wolff 2010-01-20 17:17:34 UTC 
marking as duplicate, please reopen if you can reproduce with KDE 4.4
