Description Davi 2013-03-14 01:31:37 UTC
Description of problem:
I tried to run # gsf-office-thumbnailer -i smthng.pptx -o ~/out -s 32
SELinux is preventing /usr/bin/gsf-office-thumbnailer from 'create' accesses on the file out.KRC4TW.

*****  Plugin catchall (100. confidence) suggests  ***************************

If você acredita que o gsf-office-thumbnailer deva ser permitido acesso de create em out.KRC4TW file  por default.
Then você precisa reportar este como um erro.
Você pode gerar um módulo de política local para permitir este acesso.
permitir este acesso agora executando:
# grep gsf-office-thum /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2013-03-14 10:36:52 UTC
Davi does

# restorecon -R -v /home

change any labels?

Comment 2 Davi 2013-03-14 12:38:59 UTC

Yes, but only for some files under ~/.themes, but may I guess it's not important?

Comment 3 Daniel Walsh 2013-03-14 19:00:49 UTC
Can libgsf create its content in ~/.cache/thumnails

Like the other thumbnailers?

Comment 4 Caolan McNamara 2013-03-15 11:49:35 UTC
Well, -o ~/out does ask for the final file to be written to the home dir. We can change the tmp file location I suppose, but will that actually help this example when it comes to writing that final file in the home dir.

Comment 5 Fedora Update System 2013-03-15 13:44:08 UTC
libgsf-1.14.24-3.fc18 has been submitted as an update for Fedora 18.

Comment 6 Daniel Walsh 2013-03-15 15:55:58 UTC
Caolan, does anyone other then testers use the -o command?

Comment 7 Caolan McNamara 2013-03-15 16:29:48 UTC
Its a simple enough utility, gsf-office-thumbnailer -i infile -o outfile, extract the preview images of various file formats to an output file. I don't know all the circumstances under which its called.

Comment 8 Daniel Walsh 2013-03-15 17:02:13 UTC
What I meant is, that it is probably almost always called by nautilus of the filemanager widget.

Comment 9 Caolan McNamara 2013-03-15 20:31:02 UTC
I suppose, yes, typically its major user would be nautilus.

FYI, a user is reporting problems in the form of segfaults with
with libgsf-1.14.24-3.fc18


(There isn't much there, but offline messages confirms the version number
and segfault in the form of screen shots.)
