Greetings,
Seems that this bug is affecting the latest 2.6.32-11.15 kernel in
Lucid. Running the simple C program to reproduce the failure from
comment #2 I get the following.
Without AppArmor profile:
open(/var/tmp/foo, O_RDWR|O_CREAT, 0700) = 3
ftruncate(3, 0) = 0
The Lucid kernel add some flags to provide better control over this and
other path behaviors and it looks like the flag for deleted file lookup
isn't properly being applied. It will be fixed in the next update of
AppArmor.

Dear John.
Currently firefox apparmor profile is disabled after update so bug with zotero
is not reproduced.
Should I first enable apparmor firefox profile?

Iakov,
yes you will need to reenable the apparmor firefox profile to reproduce,
however I have already had reports of issues with the patch and I am
working on a new version so I would wait for the newer version.

This is more of a bug in firefox and evinve. They are relying on
trunc(/some/path) working after the file has been deleted, instead
they should be using trunc(fd). There use of trunc is incorrect even
though it has traditionally worked because it may not get the file
pointed to by the fd. If a

There have been several people in bug #449286 that are hitting this bug.
Since the evince and firefox parts of that bug are fixed, I added a
linux task and will mark that bug a duplicate.

This bug is likely an SRU candidate. I would prefer seeing it fixed
before release, but understand if the kernel team wants to freeze their
kernel.
