Bugzilla Bug 127547

I'm getting segfaults from "attr". For instance :

% gdb --args /bin/attr -l /home/thomas/test

This patch from upstream's CVS seems to have fixed the issue:

Created an attachment (id=83097) [details]
attr-2.4.28-libattr-fix.patch

That's the upstream patch, just attaching it for convenience.


Oh, and here is the expected result of my test case:
% attr -l /home/thomas/test
Attribute "Beagle.Uid" has a 22 byte value for /home/thomas/test
Attribute "Beagle.MTime" has a 14 byte value for /home/thomas/test
Attribute "Beagle.AttrTime" has a 14 byte value for /home/thomas/test
Attribute "Beagle.Fingerprint" has a 25 byte value for /home/thomas/test

added to 2.4.28-r1, thanks
