Attached: TIFF image

LibreOffice/Linux is not able to insert the attached TIFF image in a Writer or Impress document. Error message: "Unknown graphic format".

The TIFF is a 1-bit Group-4-compressed TIFF image produced with GIMP. tiffinfo says:

TIFF Directory at offset 0x2f1c (12060)
  Subfile Type: (0 = 0x0)
  Image Width: 3156 Image Length: 1844
  Resolution: 600, 600 pixels/inch
  Bits/Sample: 1
  Compression Scheme: CCITT Group 4
  Photometric Interpretation: min-is-white
  Orientation: row 0 top, col 0 lhs
  Samples/Pixel: 1
  Rows/Strip: 64
  Planar Configuration: single image plane

Tested with LO 3.5.4.2 and 3.6.2.2 under Ubuntu 12.04 (64 and 32 bit).

Other 1-bit TIFFs work, for example one written by ImageMagick with tiffinfo

a bt at the moment bStatus gets sal_False

Bt retrieved on pc Debian x86-64 with master sources updated yesterday
Comment 4 Julien Nabet 2014-02-01 18:01:18 UTC 
Caolán: I runned a gdb session and retrieved a backtrace with master sources updated yesterday. Any idea what is wrong here?
The tiff can be read with Doc displayer (Debian testing)
Comment 5 Caolán McNamara 2014-02-07 16:09:23 UTC 
There's a gadzillion tiff extensions and features and we don't implement them all (yet). I'd *guess* we haven't implemented CCITT Group 4 compression.
Comment 6 LE GARREC Vincent 2014-07-02 09:09:43 UTC 
Is it me or this feature have been implemented in LO 4.2.4.2 ? I tried and LO succeed to load a Group 4 TIF. There's small issue with the rendering but no critical failure.
Comment 7 LE GARREC Vincent 2014-07-02 09:23:30 UTC 
Sorry for the noise. The image that I tested worked quite well with Group 4 attribute but the original enclosed image still unreadable.
