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

I closed ark while one file was opened in the preview (pdf) and I opened another large pdf. During the opening I closed ark and a bit later the first pdf closed and ark crashed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Ark (ark), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
