I installed Kdbg 2.5.1-1 from the Raring repos and it doesn't seem to do anything useful -- can't set break points or single step. I get some popup dialogs loading the executable than makes little sense (I understand English may not be the native language but the message is all wrong for the context).

The 2.5.0 version works well enough on 12.04 (Linux Mint) but pops up a few gibberish dialogs when launched from the menu.

Both would seem to be regressions from the 2.2.0 that I've been using with 10.04 for these past three years, with the 2.5.1 totally broken for me

If it works for you, any idea of what piece may have been left out of the package dependencies?
