First, sorry for my english. I updated the software version for the new version 0.5.9. After having imported some new files, Calibre began to see this error message.

[Errno 13] Permission denied: '/ (51)'
Detailed traceback:
Traceback (most recent call last):
File "/home/kovid/work/calibre/src/calibre/gui2/library.py", line 350, in current_changed
File "/home/kovid/work/calibre/src/calibre/gui2/library.py", line 318, in get_book_display_info

File "/usr/lib/python2.6/os.py", line 157, in makedirs
mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/ (51)'

I am using Ubuntu 9.04 64 bits.
Linux 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 GNU/Linux

Someone can help me with this?
Thanks in advance,

Alejandro.-
