Application: ark (2.19)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-28-generic x86_64
Distribution: Ubuntu 14.10

-- Information about the crash:
- What I was doing when the application crashed: I had two archive opened with Ark, one .rar, one .zip. I was closing one of them when suddenly was closed also the other one warning that there was an error, with the question about if I wanted to send a bug report.

The crash does not seem to be reproducible.

-- Backtrace:
