Before 1.5.0, it was possible to drag files out of file-roller into the thunar window, and file-roller would start unpacking them. In thunar-1.5.0 this doesn't work anymore. Other applications might be affected by this too.

Steps to reproduce:
1) Open thunar, open archive file (tar.bz2, tar.gz, zip, whatever) with file-roller
2) Select a file or directory and drag it out of the file-roller window into the thunar window (standard view).

Expected results:
A border appears around the standard view, indicating that thunar will accept the files file-roller feeds them. After releasing the mouse button, file-roller starts doing its work and unpacks the selected file or directory.

Actual results:
thunar rejects the file or directory, file-roller remains silent and nothing gets unpacked.
