File involved in crash
Select from the end upwards until the selection includes the "--- snip ---" line, then press Backspace -> kaboom.
What kind of mode (i.e. indentation / folding / syntax highlighting) did you assign to the file? I could not reproduce the crash, please be more specific. I did nothing manually, I just opened the file by double-clicking in Dolphin. Mode: Tools -> Mode says "Normal". Indentation: Tools -> Indentation says "None". Folding: Folding markersd are disabled in the GUI (and thus nothing is folded). Syntax highlighting: Tools -> Highlighting says "None". Encoding: Tools -> Encoding says Utf-8. Line endings: Tools -> End of Line says UNIX. How much of the file can you see when you open Kate? And you select just to the start of line 33 (i.e. just before the ---) or do you select the \n before (i.e. to the start of line 32? Do you delete with Backspace or with Delete? Do you select from start to end? From end to start? Sorry that I bug you with so many questions, but I just can't reproduce the crash (and boy, would I like to do so... a reproduced bug is nearly a fixed bug ;-)). It's ok, though I have answered some of these questions in my initial report already ;). I can see all rows, but not all columns (word wrapping is disabled, so some of the long ones extend beyond the confines of the viewport). I select from the end/bottom to the start/upwards. I select to the start of line 33. I delete with backspace. I still cannot reproduce, anyone else? Actually, it turns out that my bug report was incomplete, mea culpa. Kate does not crash after selecting from the end to the start of line 33 and pressing backspace - rather it crashes if I press backspace twice. I.e. select from the end to the start of line 33, press backspace, press backspace again. Thanks, this did the "trick", I reproduced it easily now. changing status *** Bug 223345 has been marked as a duplicate of this bug. *** SVN commit 1090734 by cullmann: BUG: 226409 try to remove segfault, now the smartrangegroups overlap in strange ways but otherwise just the wrong group got resized, its end didnt match reality and cursors belonged to groups with end lines < cursor line M +39 -3 katesmartmanager.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1090734 *** Bug 226322 has been marked as a duplicate of this bug. *** *** Bug 192606 has been marked as a duplicate of this bug. *** *** Bug 228980 has been marked as a duplicate of this bug. *** *** Bug 230001 has been marked as a duplicate of this bug. *** It would be great to have that in 4.4.2 or 4.4.3, because of the crash it causes, which in daily work with Kate becomes very annoying. *** Bug 231425 has been marked as a duplicate of this bug. *** *** Bug 233081 has been marked as a duplicate of this bug. *** *** Bug 234335 has been marked as a duplicate of this bug. *** *** Bug 234364 has been marked as a duplicate of this bug. *** *** Bug 234382 has been marked as a duplicate of this bug. *** Christoph, given this crash seems to appear very often, maybe we should consider backporting this one-liner?

Reproducably. I'm going to attach the file and point out extent of the text selection.
