Description pathematica 2010-08-31 11:42:02 UTC 
Application: kate (3.4.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I was running Kate from Gnome over Ubuntu 10.04. I was creating Octave scripts which had suffix *.m. I was seeking a way to make Kate automatically recognise *.m files as Octave (rather than MATLAB) so that it would automatically apply appropriate highlighting (I can obtain the correct highlighting for Octave files individually - I was trying to find a way to make this apply to all files of this type). I was in "Settings|Configure Kate|Open/Save|Modes&Filetypes|MIMEtypes" I had edited the entry "MATLAB script/function" to "Octave script/function". The crash occurred (reproducibly) on pressing either "OK" or "Apply". I apologise if I was misguided in my attempt to associate *.m files with Octave in this way and I was trying to do something that might appear dumb to those with more insight!

The crash can be reproduced every time.

Reported using DrKonqi
Comment 1 Chaos A.D. 2010-09-01 20:09:21 UTC 
This crash also reproduced when using kate as part of KDevelop
Comment 2 Dario Andres 2010-11-21 17:42:42 UTC 
[Comment from a bug triager]
I can reproduce this crash here using KDE SC 4.5.3

Steps to reproduce:
- Open Kate
- Go to Settings/Configure Kate
- Go to Open/Save
- Go to the Modes & Filetypes tab
The selected Filetype in the ComboBox is "Normal". The fields below are empty.
- Press the "magic wand" button near the "MIME types" line edit, near the bottom of the dialog
- In the new dialog, look for the "MATLAB script/function" item in the list (it is inside the "text" class item)
- Click the "Edit" button on the bottom of the dialog
A KEditFileType dialog appears
- Change the description of the type (it may be any string; the reporter suggested "Octave script/function")
- Click Apply or OK
Kate will crash on background while the file types are being updated
The KEditFileType dialog will properly close after that

- Backtrace (KDE SC 4.5.3):
