python key error ubuntu 18.10

[reginaldc]

Hi,

I have this error when trying to import photos:

KeyError: '.'
Traceback (most recent call last):
File "/home/reginald/.local/share/QGIS/QGIS3/profiles/default/python/plugins/ImportPhotos/ImportPhotos.py", line 368, in ok
self.extension = self.extension_switch[self.extension]
KeyError: '.'

I also noticed that if I chose geojson as output format the plugin creates a file named fotos.geojson.shp which is a shapefile.
Do I need to install additional python libraries?

Regards,
