deleting multiple books error

[Eli Schwartz]

for some reason, whenever I run calibre later than 0.9.x and try to delete multiple books, I get a really weird error.
I'm now on calibre 1.6, running Ubuntu 12.04 LTS, and I still get the error.

It "refuses" to delete the dooks, but they are gone from the file explorer. A second delete gets rid of them. However, in the process, the parent folder of the library (Calibre Libraries) fills with such fascinating files as (using copied test library Testy):
Testy deleted 8vB8l3
Testy deleted DNnrAl
Testy deleted f8oDvZ
Testy deleted gGj7vz
Testy deleted GJZCjt
Testy deleted M7_Rbl
Testy deleted n66qWB
Testy deleted PC1uQh
Testy deleted rXjSzN
Testy deleted t1pFzB
Testy deleted WIdDdl
Testy deleted wOnkA1
Testy deleted zk9Z67

Error message is as follows:

Error: Failed to delete
Failed to delete some books, click the Show Details button for details.

For some reason, your OS is raising permission denied (EPERM) errors
when calibre tries to delete a non-empty directory, instead of
ENOTEMPTY, which is causing the problem. Do you have your calibre
library on some kind of special filesystem?

In any case, I have changed the code to not rely on the OS sending the
proper error code, it will now manually check if the directory is empty.
That should fix your problem.

Thanks.
