Application: muon (0.5.0)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-13-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
1) open muon
2) select 'Editors' category
3) select 'ada-mode'

actually it seems to crash when selecting any package that is pinned down to -1 and thus has no installation candidate

- Custom settings of the application:
ada-mode is only available on debian stable that I have in my sources.list and pinned down to -1
ada-mode:
  Installed: (none)
  Candidate: (none)
  Version table:
     3.6-2 0
         -1 http://ftp.de.debian.org/debian/ stable/main amd64 Packages
