Application: ark (2.16)
KDE Platform Version: 4.6.00 (4.6.0) "release 395"
Qt Version: 4.7.2
Operating System: Linux 2.6.34.7-0.7-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
Downloaded WordPress 3.1 to install into localhost. Extracted archive into /srv/www/htdocs/wordpress (permissions valid for this folder). Had closed existing WordPress install, but browser was still open (so Apache was likely running). Ark asked whether to overwrite existing files; I told it to overwrite all. A few seconds passed before Ark crashed. 

Did the extract a second time, with no issues.

-- Backtrace:
Application: Ark (ark), signal: Segmentation fault
