Space in folder name results in buggy behaviour

[Georacer]

I found another bug in file_browser today, sorry if I start looking pedantic. If navigating in a path containing a space, file opening behaviour is erratic.

Steps to reproduce:

1. Create path and file:

   :~$ mkdir test\ folder
   :~$ cd test\ folder/
   :~/test folder$ touch test_file.txt
   :~/test folder$ echo "example content" >> test_file.txt 
   :~/test folder$ cat test_file.txt 
   example content

2. Launch file_browser and select gedit to open files:
3. Navigate to directory and select file:
4. gedit opens two files and none of them is the correct one:

Yeah, I noticed that as well while fixing the other stuff. I have a fix for this already, I'll push it soon.

Don't worry about opening too many issues, I appreciate the feedback.

Tested and working fine!
