+Subject: [PATCH 1/3] Use QFileDialog for selecting directories
+
+KFileWidget is not as good at selecting directories as KDirSelectDialog
+from plasma-integration. On top of that, directory selection appears to be
+entirely broken currently.
+
+Use KDirSelectDialog through QFileDialog if possible.

+Subject: [PATCH 3/3] fuse fileopen urls on-demand
+
+instead of restricting ourselves to file urls we now accept any url
+(within the limitations from kprotocols ultimately) but then fuse them
+into the local file system using kio-fuse. this enables us to pass smb:
+and sftp: and whathaveyou urls into the sandbox without the sandbox
+having to worry about anything
