--shell on windows crashes due to spaces in inkscape pathname

[Stephen Parry]

Inkscape 0.91 r13725 64 bit
Windows 10 Pro 64bit version 1607 build 14393.222

When inkscape is installed in its default directory (c:\program files (x86)\Inkscape or c:\program files\Inkscape) and executed by full pathname with --shell, shell mode gets confused and bombs out with warnings when commands are issued.

Steps to reproduce:
1. create a simple svg called shell_test_0.svg with a few shapes in
2. open a command prompt in the directory containing the test files
3. Enter this command to enter shell mode:

 "c:\Program Files\Inkscape\inkscape" --shell

Note that the quotes are required to work around Redmond's twisted notion of what makes a good folder name for executables. Different placement of the quotes causes variations of the bug, but no workaround.

4. The shell will open:

 Inkscape 0.91 r13725 interactive shell mode. Type 'quit' to quit.
 >

5. In shell mode enter the following:

 --query-all shell_test_0.svg

6. The shell produces the following output and then exits unexpectedly:

** (inkscape.exe:8560): WARNING **: Can't open file: FilesInkscapeinkscape (doesn't exist)

** (inkscape.exe:8560): WARNING **: Can't open file: FilesInkscapeinkscape (doesn't exist)

** (inkscape.exe:8560): WARNING **: Specified document FilesInkscapeinkscape cannot be opened (does not exist or not a valid SVG file)

Thanks for taking the time to write a report!

Reproduced on Windows XP (32-bit), lp:inkscape/0.92.x rev. 15207.

[Alvin Penner (apenner)]

on Windows 10, Inkscape 0.92pre3 15195,
replacing the backslash with a forward slash will work:

- for example, the command : >--query-all \windows\temp\catan.svg fails.
- but the command : >--query-all /windows/temp/catan.svg succeeds

@Alvin No: It's the _program_ path that is the problem, not the svg file path. Look at my example. I did not use a path for my svg at all.

@jazzynico: This may be how I have the program installed on my system, but preview 2 will not --shell at all. It just returns to the console. No command line args seem to work at all.
