application won't launch

greetings all,
i have got a few applications that i cannot launch anymore. i am pretty certain i was in the past, but when i try now, it looks like as if the process starts (like the app shows up in the control bar and the icon is bouncing on the desktop), but then it just quits. seems to be happening more often after i ran through an upgrade. also tried reinstalling those particular packages, no improvement. gladly accept some suggestions.
thanks, theo

Run the various applications from the command line and paste the output.

as you can see, luvcview works fine, but so did frostwire, cheese … webKam and camorama never launched for some reason.
