Win7, client 2.5.0, replacing more than 47 files at a time by virtual files impossible

[sorenweber]

Expected behaviour

I select 48 files (jpeg-photos) or more, right-click and select ownCloud->Replace file(s) by virtual file, and the files will be replaced by virtual files.

Actual behaviour

If I select 48 files or more, nothing happens. If I select 47 files or less, it works.

Steps to reproduce

1. Select 48 files or more in Windows Explorer
2. Right-click and select ownCloud->Replace file(s) by virtual file
3. Observe that nothing happens

I just realize there is a 4K buffer that need to contains the concatenation of all the filename.
So if all the file names is bigger than about 4000 character, this won't work.

@sorenweber Can you verify the fix using a 2.5.1 daily build? Thank you

I have verified the fix, and it works (both ways, i.e. replacing files with virtual files, and vice versa). I had to perform the recommended reboot after installation. Thank you!
