Installed from:    Compiled sources

When I right-click a link to a .ps file and hit 'Open in Background Tab', it opens in a background tab, but Konqueror seems to think it's in the foreground; its toolbars are activated, and the navigation buttons (Back, Forward, Up) act on the background tab not on the displayed tab.

Further, if one then closes the background tab, many actions on the foreground tab cause konqueror to crash, due to the KonqView it's trying to access being NULL. Interesting part of backtrace:
