Public bug reported:
- Ubuntu 16.04 (Xenial Xerus) Daily Build
- AMD64
- Unity
Steps to reproduce:
- a folder with thousands of files (here about 15000 files with a overall size
of 1.5 GB)
- delete files to trash
- right-click at the trash icon
- click empty trash
A dialog "Dateioperationen" shows "vorbereiten" (it's German, I think in
English the dialog has the title "file operations" and shows the text
"prepare").
This happens at this point:
- the dialog remains unchanged
- the process gvfsd-trash consumes up to 75% CPU, see output of top
After 30 minutes of waiting for any reaction I killed the process. The
trash still contains all the files.
