Bug ID: 486623
Summary: Opening this 909kb file in Kate causes it to leak

OS: Linux
Status: REPORTED
Severity: crash

File that causes the leak
SUMMARY
The attached file is a config file from the game Colin McRae Rally 2005. I
thought it would just be a text file so I tried opening it in Kate, it turned
out to be a binary file, but instead of simply showing garbled text, Kate locks
up, starts leaking memory and eventually gets killed by OOM (or crashes the
whole system if you don't have OOM).
STEPS TO REPRODUCE
1. Open Kate (or KWrite or any application like Ark that previews unknown files
as text)
2. Drag the attached file into it
3. Watch RAM usage
OBSERVED RESULT
Kate freezes and fills up the entire memory
EXPECTED RESULT
Garbled text
