Specifying a file without extension causes Qtractor to stop responding

Platform: Fedora 25
Software: qtractor 0.8.0
Source: Fedora repository

Observed behavior:
* reboot machine (superstition, and to ensure "nothing" else is running)
* start qJackCtl
* start qtractor
* File :: Save As
* Use 'tutorial' as the file name
* Click OK
* Qtractor stops responding

Expected behavior:
* Qtractor automatically adds the ".xml" extension or...
* Qtractor notifies the user that this is an error and how to correct it.

I discovered the solution (using .xml at the end of name) while testing my bug report. Thought I would pass this along anyway.

I find Qtractor really appealing. Thanks for making it available!

PS: Actually, I'm continuing to have problems with Qtractor becoming non-responsive. It seems to be connected with the file selection dialog. For example,
(1) I can open a saved project file, but only by selecting it from "Recent Files".
(2) When I start Qtractor and select "File :: Open::, the dialog doesn't show session files that I can select (I used a .xml extension, as I explained above)
(3) When I import a .flac file into an track, Qtractor stops responding. After force quit and restart of Qtractor, the track is there with the correct audio file.

Lemme know if there's anything I can do to help figure this out. Thanks again, n
