Summary: Repeatable crash editing JavaScript document
Product: kate
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general

Sample document that causes Kate to crash.
Kate crashed while editing some JavaScript code. I was able to trim the file
down quite a bit and still have Kate crash whilst editing it.
Steps to reproduce:
1. Load the file
$ kate crash.js
2. Position the cursor at the end of line 13, after "});"
3. Press enter. Kate crashes.
Application: kate (16.12.3)
Qt Version: 5.7.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.5-100.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs
The crash reporting assistant indicates the backtrace does not have enough
information, though I've added all debuginfo packages to my system. It's
pasted below in case it's useful nonetheless.
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
