Sentry Crash Report:

Description Thiago Jung Bauermann 2014-01-20 23:11:25 UTC 
Application: kate (3.12.0)
KDE Platform Version: 4.12.0
Qt Version: 4.8.2
Operating System: Linux 3.2.0-58-generic-pae i686
Distribution: Ubuntu 12.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I started a Kate session containing remote files being accessed via the fish kio. As soon as Kate loaded, I pressed Ctrl+O while the current bufferwas displaying the message "The file foo is being loaded.". Kate crashed immediately. This happens everytime.

If I wait until the file is loaded. Kate doesn't crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Its a ugly crash, unfortunately, I am never able to reproduce it. If there is some way to do so, please reopen. Perhaps retry with the KF5 based version, for sure has more fixes.
