Bug Description

Using Ubuntu Maverick 64 Bit Desktop Edition with the default Gnome Desktop.

When I connect an ftp directory using the Nautilus File Manager I experience the following problem:

When I try to edit a file opened from the ftp share and then save it again, I get a timeout error and the file on the server gets truncated to 0 Bytes.

This happens every time - 100% reproductible.

once again the error occurs only when using kernel 2.6.35-22 , with 2.6.32-25 kernel from Lucid everything works as intended.

I think this bug is related to Bug #662361

everything works as intended.

So the Bug must have entered some where between Version 2.6.32 and 2.6.33.
since 2.6.33 all the tested kernels have the same Bug.

Now I tried
Linux C521 2.6.35-02063507-generic #201009290909 SMP Wed Sep 29 09:11:05 UTC 2010 x86_64 GNU/Linux
on my other amd64 machine it has Lucid Lynx installed.

The Bug is also just the same here.

So using the mainline 2.6.35 kernel on Lucid 64 Bit is just the same as with Maverick

Now I did al lot more test,
amoung others I tried a Ubuntu 10.10 64bit Live CD with gedit.

And my Buggy Maverick System with more Editors.

I come to the conclusion that Geany and Scite Editors are more likely to produce the Bug that the gedit.

With the LiveCD and gedit I was not able to produce the bug.

On my System I gedit sometimes also produces corrupt files sometimes it works.

I now think the bug might be related, or even a duplicate of Bug #658069 a bug in fuse.
