Subject: Bug in 2.6.29-rc1 using NILFS

Hi,

My laptop threw a bug when I opened claws-mail in 2.6.39-rc1.
My home partition uses a Nilfs2 filesystem.

The operating system continued working after a long pause, 
which could have been 30 seconds I guess.  I didn't try to do
anything else, just re-booted back into .38.

This is what the log captured:-
