NOT WORKING since v0.9.4

I use calibre portable since a long time - don't know which version.

CalibrePortable + CalibreLibrary are located on an a networkshare on a Windows 2008 R2 x64.

The last version i can use is 0.9.3 There everything works fine.

With newer versions ( => 0.9.4 i get this error when i add and edit metags for books:

------- BEGIN -------
Traceback (most recent call last): File "site-packages\calibre\gui2\dialogs\metadata_bulk.py", line 124, in do_one_safe

------ END ------------

When i copy back the backup of v0.9.3 everything works fine again.


Thanks in advance
