Description Sebastian Dicke 2017-04-11 19:52:35 UTC

Versions:
Kate: 16.08.3
KDE Frameworks: 5.28.0
Qt: 5.7.1
Kernel: 4.9.0-2-amd64

Steps: 
1. Mount a filesystem via sshfs.
2. Open a text file saved in this filesystem via dolphin.
3. Kate shows the content.
4. Kate crashes.

It do not matter if the cursor get moved. File opening from the same filesystem with other applications causes no problems. The bug is reproducible, I tried the same with different files more than 10 times. This bug do not occurs with file saved on a SSD connected the the motherboard.

Stacktrace:

Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
