[Old Thread] Strange Calibre portable Issue

i have a strange issue in Calibre portable > 0.9.0, in 0.8.x i don't have the problem.

Context :
i use Calibre for manage my comcis/bs/manga collection, when i import a new comix the first image became the cover.
My calibre installation are placed on my NAS and i execute calibre from my cifs share.

extension type : pdf, cbr and cbz

Problem :
if i add a new book just after upgrade the cover generation i ok. but if i close Calibre and re-execute then the generation of cover failed. (and the fix cover in edit metadata don't work too).
in debug mode i have this error :
calibre Journal de débogage
calibre 0.9.3 Portable

('Windows', '7', '6.1.7601')

if i re-install Calibre the first execution work but all other don't generate cover ... is really strange
