Reported using DrKonqi 915157 1 40698 hein 2010-02-11 22:35:50 +0000 Created attachment 40698 File involved in crash Select from the end upwards until the selection includes the "--- snip ---" line, then press Backspace -> kaboom. 915273 2 mail 2010-02-12 01:31:22 +0000 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. 915274 3 hein 2010-02-12 01:39:10 +0000 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. 915275 4 mail 2010-02-12 01:52:37 +0000 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 ;-)). 915277 5 hein 2010-02-12 01:59:46 +0000 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. 915278 6 mail 2010-02-12 02:18:03 +0000 I still cannot reproduce, anyone else? 915279 7 hein 2010-02-12 02:23:51 +0000 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. 915282 8 mail 2010-02-12 02:32:55 +0000 Thanks, this did the "trick", I reproduced it easily now. 915283 9 mail 2010-02-12 02:33:34 +0000 changing status 915286 10 mail 2010-02-12 02:34:51 +0000 *** Bug 223345 has been marked as a duplicate of this bug. *** 917747 11 christoph 2010-02-15 23:25:50 +0000 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 918143 12 christoph 2010-02-16 12:56:29 +0000 *** Bug 226322 has been marked as a duplicate of this bug. *** 918458 13 dhaumann 2010-02-16 18:31:13 +0000 *** Bug 192606 has been marked as a duplicate of this bug. *** 926785 14 dhaumann 2010-03-01 18:02:27 +0000 *** Bug 228980 has been marked as a duplicate of this bug. *** 935809 15 dhaumann 2010-03-17 21:46:34 +0000 *** Bug 230001 has been marked as a duplicate of this bug. *** 936031 16 kay.abendroth 2010-03-18 11:37:47 +0000 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. 937132 17 dhaumann 2010-03-20 17:57:06 +0000 *** Bug 231425 has been marked as a duplicate of this bug. *** 943977 18 dhaumann 2010-04-02 19:21:39 +0000 *** Bug 233081 has been marked as a duplicate of this bug. *** 949553 19 dhaumann 2010-04-14 19:43:31 +0000 *** Bug 234335 has been marked as a duplicate of this bug. *** 949559 20 dhaumann 2010-04-14 19:47:15 +0000 *** Bug 234364 has been marked as a duplicate of this bug. *** 949596 21 apaku 2010-04-14 21:17:49 +0000 *** Bug 234382 has been marked as a duplicate of this bug. *** 949628 22 dhaumann 2010-04-14 22:25:38 +0000 Christoph, given this crash seems to appear very often, maybe we should consider backporting this one-liner?
