How reproducible:
100%

Steps to Reproduce:
1. start gimp and make a complex multi layer image
2. save as xcf
3. open the xcf
4. Gimp error: XCF: This file is corrupt!  I have loaded as much
of it as I can, but it is incomplete.
  
Actual results:
XCF: This file is corrupt!  I have loaded as much of it as I can, but it is
incomplete.

Expected results:
Gimp operating on the opened file

Comment 1 Chuck Ebbert 2007-11-27 00:53:16 UTC

kernel-2.6.23.8-34.fc7 is in updates-testing with this fix applied.

You can update with:

 # yum --enablerepo=updates-testing update kernel

Comment 2 Rolf Fokkens 2007-11-28 19:23:33 UTC

Problem seems to be solved this way.

Comment 3 Ade Rixon 2007-11-30 07:53:13 UTC

The bug title is slightly misleading; I'm seeing this with NFS v3 as well. It
affects LightZone 2.4 for Linux when exporting TIFF files (the files are
unreadable by libtiff-enabled applications due to "zero scanline size").

Comment 4 Alexandre Oliva 2007-12-03 05:15:50 UTC

Any idea of how much longer this data-corruption problem explicitly fixed in the
Fedora 8 kernel (on Nov 7), commonly exercised by backup programs (rsync -S) on
commonly-used filesystem types (nfs) going to remain in the most up-to-date
stable kernel available for Fedora 7?

Comment 5 Chuck Ebbert 2007-12-04 18:57:26 UTC

2.6.23.8-34 is being released ASAP.
It has been available in updates-testing for over a week...
