Screenshot of saving document to tmp folder when opened from Lotus Notes

Problem description: 
Documents opened from webmail application are saved in a temporary directory. After reboot or some time, this folder is emptied (hence the name "temporary" directory), losing the users document.

Steps to reproduce:
1. Create document
2. Email document to yourself
3. Open the document directly from within webmail or email client (tested on gmail and lotus notes)
4. Save the document
5. Go to the application's temporary folder and locate the document. (or click "Save As" and note the location)

Current behavior:
When a document is opened from most webmail/desktop email clients, the working copy is stored in a temporary folder. When the user saves this document, it is saved in the temporary folder. 

Expected behavior:
The save button function in LibreOffice should inspect the path and if it finds the word: TEMP, TMP, tmp, temp, temporary, etc. (a regular expression would probably be good here) in the path it should either:
1) warn the user that this is a temporary location with a message "Are you sure you want to save here? "
or
2) Pull up the "Save As.." dialog with the path set to the default save location, eg Desktop directory, Documents directory, etc
