[ubuntu-mono] [Bug 551086] Re: [Lucid] F-Spot NullReference Error while transferring photos from Kodak camera

[Michael Mess]

I think there are two bugs here:

One in FSpot as it doesn't check a value for a NullReference before
using it and one outside of FSpot in a library used by FSpot which leads
to the delivery of a NullReference.

To fix the first bug, FSpot should be enhanced to check values returned
by external libraries before actually using them.

The second bug which causes a NullReference might be this:

Title:
  [Lucid] F-Spot NullReference Error while transferring photos from
  Kodak camera

Status in “f-spot” package in Ubuntu:
  New

Bug description:
  Binary package hint: f-spot

  F-Spot testing found an unhandled exception while copying images from
  my digital camera...

  The camera is a Kodak EasyShare 875.  On connecting the camera to my
  netbook, fspot opened the dialog for importing photos.  I added a tag
  "Kodak Pix" and started the import.

  After a short while (shortly into copying the 35 pictures over,) I got
  an error popup that says:

  Unspecified Error
  Error GeneralError: LibGPhoto2.GPhotoException: Unspecified error
    at LibGPhoto2.Error.CheckError (ErrorCode error) [0x00000]
    at LibGPhoto2.Camera.GetFile (System.String folder, System.String name, CameraFileType type, LibGPhoto2.CameraFile camera_file, LibGPhoto2.Context context) [0x00000]

    at FSpot.CameraFileSelectionDialog.SaveFile (Int32 index) [0x00000]
    at FSpot.CameraFileSelectionDialog.Download () [0x00000]

  Repeated attempts at clicking Retry or Skip did nothing.  Cancel
  canceled the operation and opened a new error box that said the
  following:

  F-Spot Encountered a Fatal Error
  System.NullReferenceException: Object
  reference not set to an instance of an object
