Scan save does not work

[kaklik]

In case of use File -> Save as option. The Scanner utility declares the "Status: Saving..."

But, the produced file has zero size

$ ls -la | grep rfs
-rw-rw-r--  1 kaklik kaklik        0 dub 10 13:04 Scan 150.0-500.0MHz_chotilsko.rfs
-rw-rw-r--  1 kaklik kaklik        0 dub 10 12:53 Scan 150.0-500.0MHz_praha.rfs
-rw-rw-r--  1 kaklik kaklik        0 dub 14 11:28 Scan500-1000.0MHz_chotilsko_noANT.rfs
-rw-rw-r--  1 kaklik kaklik        0 dub 10 09:19 Scan80.0-120.0MHz_praha.rfs

Terminal output is:

Traceback (most recent call last):
  File "/home/kaklik/programy/RTLSDR-Scanner/rtlsdr_scanner/main_window.py", line 485, in __on_save
