Description:
Attempting to save a mysql workbench model previously stored on a gvfs mount in Ubuntu results in the following error message:  "Could not save document to /run/user/1000/gvfs/sftp:host=sinogomphus/srv/www/swifteration.com/switertation.mwb  Error writing zip file: Seek error: Operation not supported".  The *.mwb file is then written to a *.mwb.bak file with no new, updated *.mwb created.

How to repeat:
Create a gvfs mount on ubuntu (the easiest method is to attach to an ssh server using nautilus on ubuntu).  Then save an new model on the gvfs mount or move the model to the gvfs mount (this step will work).  Then, open the model and attempt to save it.  The error message in the description will come up.

Suggested fix:
The easiest fix might be to offer an option to stop backups on saving.  If not, then allow saving to a gvfs mount.

Thank you for the bug report.
