Whoops, spoke to soon. 0.6b7 completely breaks bulk conversion of files. If I do a batch of 150 or so, it converts #1, #2, and #150 fine, but all the others fail:
Code:
Convert book 149 of 150 (u'Creative Couplings Book 2')
Traceback (most recent call last):
File "worker.py", line 103, in <module>

IOError: [Errno 2] No such file or directory: 'c:\\docume~1\\owner\\locals~1\\temp\\calibre_0.6.0b7_vxl1jp.opf'
Note that ALL of the .opf files in the error messages have the same name, rather than different names, which could be the reason.
Calibre itself eventually crashes after a few minutes of generating all those error boxes with 0xc0000fd.
