Lit files will not open in the viewer in the new 0.8.51 version

[David Yearsley]

I downloaded and installed the latest version of Calibre Portable (0.8.5.1) this morning and the eBook viewer will not open any .lit files. I switched back to 0.8.5.0 and it works just fine. It tries to open but then gives the error: "I/O operation on closed file".

Here is what I get when I click Show More:

0.8.5.1 will still convert the .lit file but the eBook viewer will not open the file.

I tested this by doing fresh files for each 0.8.5.0 and 0.8.5.1 and a fresh import of a book 0.8.5.0 would open the file I chose where 0.8.5.1 would not open the book.

Fixed in branch lp:calibre. The fix will be in the next release. calibre is usually released every Friday.
