Description Daniel Franke 2008-11-23 13:41:04 UTC 
Version:           3.1.3 (using 4.1.3 (KDE 4.1.3), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.25-gentoo-r8

Marked a large portion of highlighted text from somewhere in the middle to the very end, pressed enter and got a semi-useful backtrace ...

Application: Kate (kate), signal SIGABRT

Comment 1 Dario Andres 2008-11-23 15:04:57 UTC 
This bug seems to be related to bug 161113. Same description , different ASSERT (but this assert is described also in the same bug (bug 161113 comment 4))
Comment 2 Dario Andres 2009-01-16 15:55:54 UTC 
*** Bug 180977 has been marked as a duplicate of this bug. ***
Comment 3 Thomas McGuire 2009-02-01 21:21:58 UTC 
I just had the same crash (in KDevelop) with r918271 of kdelibs trunk.
Comment 4 Thomas McGuire 2009-02-01 21:35:05 UTC 
Created attachment 30837 [details]
File where the problem happens

With the attached file, do the following to reproduce (I tried in KWrite):
1. Fold in line 16 (class Vector3)
2. Select lines 202 to 252 (including both)
3. Press the delete key
4. CRASH
Comment 5 Dario Andres 2009-12-30 17:47:25 UTC 
Here using:

Qt: 4.6.0 (kde-qt master commit 747ff8e6ef6f5a1163dfa75bc9ac4755ce7083d1
        Date:   Tue Dec 15 11:58:13 2009 +0100)
KDE Development Platform: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
kdelibs svn rev. 1067378 / kdebase svn rev. 1067378
on ArchLinux i686 - Kernel 2.6.31.6

I can reproduce the crash using the steps mentioned on comment 4.
