SUMMARY

My Enviroment is XCFE + KDE.

When I try to open a webpage, its not opened in konqueror, but in Firefox.
Open pages worked fine (last used it some weeks ago), so something must have changed due one of the last package updates, as I have not changed the OS preferences.

When I change the OS standard application from firefox to e.g. w3m, konqueror starts w3m in a consoleWhen I change the OS standard application from firefox to konqueror, opening a page in konqueror spawns new windows until I kill the parent thread

STEPS TO REPRODUCE
1. Open konqueror
2. open a webpage (via addressbar or menue)

OBSERVED RESULT
Page is opend in default application e.g. firefox, or spawns new windows in case of konqueror

EXPECTED RESULT
Just load the page in konqueror, no matter what is the default application (like it was some weeks ago!)
