Incorrect ZIP password

When a ZIP file is password protected, and i entered the wrong password, i get a message:

The password you have entered is incorrect.
Enter the correct password.

BUT, when i enter the correct password (second time), i allways get this error message:

An error occured copying [filename]:
Incorrect description code. (ZIP Error 44)

I tried this with several password protected ZIP files created with DOpus.

Is this a bug?

Yes it's a limitation of the Zip library we use, however we hope to fix this in the future.
