Seen in both 2.14 and master

Open Python Console (in Plugins menu)
Click 'Show Editor' button (little notepad icon)
In the editor widget, above the Untitled-0 tab there is a Save As button (floppy with pencil), which IS enabled, while the Save-button is NOT
Clicking that SaveAs button throws the following exception:

In Master

TypeError: join() argument must be str or bytes, not 'QDir' 
Traceback (most recent call last):

    (funcname, s.__class__.__name__)) from None

In 2.14

Python version: 2.7.13 (default, Jan 19 2017, 14:48:08) [GCC 6.3.0 20170118] 
QGIS version: 2.14.16-Essen Essen, 7bc1bc4119 

In 2.14 it is NOT always, so it is apparently depending on some kind of 'starting' directory or so?
2.18 seems to work
Master always throws Exception with me here.
