            Bug ID: 50430
           Summary: winedbg crash reporter dialog shows 'winedevice'
                    process name as 'unidentified'
           Product: Wine
           Version: 6.0-rc4
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: trivial
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs(a)winehq.org
          Reporter: focht(a)gmx.net
      Distribution: ---

Hello folks,

as it says. When a kernel driver crashes the 'winedevice' hosting process,
winedbg's crash reporter dialog has the title '"The program (unidentified) has
encountered a serious problem and needs to close. We are sorry for the
inconvenience."'

It's not really a problem since the crash dialog contains information that
points to the crashing process. But most users won't figure that part out.
