2.6.6 breaks kmail (nfs related?)

[Andreas Amann]

Hi,

I upgraded from vanilla 2.6.4 to vanilla 2.6.6, using the same compiler 
(gcc-3.3.1) and .config file (shortened version in attachment) for both. Now 
I cannot send messages with kmail and  I get the following error messages:

...
kmail: Error: Could not add message to folder (No space left on device?)
kmail: WARNING: KMail encountered a fatal error and will terminate now.
The error was:
KMFolderMaildir::addMsg: abnormally terminating to prevent data loss.
...

Apparently kmail thinks that my /home device is full, but it is not (still 
~37GB  free). Other programs have no problem writing into my home. 

Maybe kmail uses some kind of lock before writing to a folder? (I have fam 
enabled.) Is it possible that this broke recently?  

My home directory is mounted via udp-nfs from a server running vanilla 2.4.25 
with a  reiserfs on  a hardware raid. The mount options on the client are 
hservnlds:/home /net/hservnlds/home nfs 
rw,nosuid,nodev,v3,rsize=8192,wsize=8192,hard,intr,udp,lock,addr=sservnlds 0 
0

Any hints? This looks like a reproducible regression between 2.6.4 and 2.6.6 
to me. I can do more tests on request. 

Andreas
