mageia It's not reproducible that easily. Can you give more details on how to reproduce it? Also, please enable the debug media and install qt4-debuginfo, kdelibs4-debuginfo, and kate-debuginfo and post the backtrace again. Created attachment 6795 [details]
Newly created text file with Dolphin
- Step 1: in Dolphin, right click -> create a new -> text file - Step 2: open the newly created file with Kate or Kwrite - Step 3: see the crash Alternatively, you can open the attached file Debug stack trace: Application: Kate (kate), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Which debug packages? I already installed the debug packages requested above in comment #3 and put the new stack in comment #6. Are you able to reproduce this bug with attached file 6795? It seems that KMimeType::findByContent (&testMime) return null in that case.

(none) I try by myself to progress on this issue. I was able to rebuild kate with -O0 -g, but not kdelibs4 (optflags is overwritten in c++ command line). Can you please tell me what to add in the spec file to build kdelibs4 with -O0 -g? In addition, can you tell me why Dolphin creates a non empty text file (it contains "\n ") when using the right click menu "Create a new"-> "text file"? Disappeared Status:
