Precisely.

[Bug 124211] Re: touch (do_utimes) causes NULL pointer dereference
I get this as well. I'm on ext3 - latest gutsy packages (Kernel is 2.6.22-7). For standard files everything is fine - however I see problems touching files which aren't owned by the logged in user - but should be writeable by them. In this particular case file ownership is: $ stat Dordogne\ -\ 2007\ 183.jpg File: `Dordogne - 2007 183.jpg' Size: 568711 Blocks: 1120 IO Block: 4096 regular file Device: 801h/2049d Inode: 5374316 Links: 1 Access: (2674/-rw-rwsr--) Uid: ( 1001/documents) Gid: ( 1001/documents) The logged in user is a member of the group "documents".

You're not at the sprint tomorrow? Also, I now have 3 inodes that do this. A package (entirely userland) I'm working on creates them every once in a while, so it should be possible to track down what triggers it. -- touch (do_utimes) causes NULL pointer dereference https://bugs.launchpad.net/bugs/124211 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
