Bugzilla Bug 109642

The gam_server process is started by Gnome 2.12, but it does not come up
properly. /var/log/user.log repeats saying:

I'm also seeing that gam_server / gamin crashes all the time.

corruption (fasttop): 0x08066670 ***

In a terminal I started dvdrip and get a lot of these messages:

end from FAM server connection
invalid length 10794
invalid length 10794
invalid length 10794
invalid length 10794

did some quick investigating and will get back later, see this redhat bug:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=168744

Creating a .gaminrc with content

fsset nfs kernel

as suggested by the RedHat bug report makes the repetitive log-messages
dissappear and gam_server does not change the PID that often any more. I should
add, that my $HOME is imported from a NFS server.

Yet, directory content view for example in Nautilus is not updated until i
explicitely request refresh (using menu or Ctrl-R).

Just as a data point, a user on IRC had this problem, and fixed it by
re-emerging gamin, gnome-vfs, and nautilus.

I've added gamin-0.1.6-r1 to fix this issue, masked for now.  Could someone
with
the problem try that and verify that it fixes it?

1.6-r1 seems to work for me! Tried several, mount/umount touch/rm actions, that
surely would have crashed 1.6 without problem. Thanks!

In theory this should have been assigned to me.  Anyhow, please add the patch
to
the redhat bug report so that it can be fixed upstream ...

This new version works for me as well.  Tested with amarok,
gnome-volume-manager
and nautilus (which usually all killed it or at least spat out errors)

Seems to work for me too (with gnome-2.10.2 and nautilus-2.10.1-r1):

Another happy patch user.
Before the patch we had crashes hundreds of time a minute!

re comment #8:
It came from upstream, and has already been applied to CVS.

I've unmasked the fixed gamin.
