URLs with file schema do not work

[leastcommonancestor]

URLs with file schema for links to local files and directories (e.g. file:///<local path>) do not work, neither if the link is part of the "Comments" field, nor if the link is generated by a rule to convert an identifier to a link.

Calibre version: 2.57
OS: Ubuntu 15.10

I cannot reproduce this, on my linux system. Steps I tried:

1) Click Edit metadata
2) Click the insert link button
3) Click the browse for file on your computer button
4) Choose a file
5) Click OK
6) The resulting link in the Book Details panel opens the previously selected file.

Remember that for a file to be opened when you click it, you need to
have a non-broken implementation of xdg-open on your system

Sorry, my bad. I expected the action to be opening a browser tab.
Instead the action was to open a file manager window, which I did not
notice, since the file manager already showed the expected directory.
However, I found another (presumed) bug: If the file path contains
special characters (e.g. Umlaut-ö) and I enter such an identifier via
"Edit Metadata" (e.g. adding "extern:Lexika/Bibliographie der
österreichischen Zeitschriften 1704-1850/"), after clicking "Ok" I get
an exception:

The same exception is produced later every time, when I select the
corresponding book.

If I change the identifier to URL-encode the offending character (e.g.
"ö" → "%C3%B6"), the link does not work and there is no error indication.
The same happens, if there is an error in the path (e.g
"extern:Lexika/Bibliographie der sterreichischen Zeitschriften
FOOBAR/"). There should be some error indication. I would prefer, if all
URLs would be opened in a browser tab, because then the path and a "File
not found" error message would be shown in the browser tab.

Thank you for your quick response.
