Preview is not shown when filename contains colons

[nivit]

Describe the bug

1. the original image is not shown when the temporary directory contains a dot.
2. the preview of the new/converted image is not shown when the filename contains colons

To Reproduce

Steps to reproduce the behavior:

1. mkdir ~/.tmp
env TMPDIR=~/.tmp fotokilof
   (load an image)
   In the log file ~/.fotokilof.log appears the message:

*** ERROR: preview_orig: Cannot load preview

2. Try to load an image whose filename contains a colon; then the image is loaded, but when you execute a transformation the preview of the new image is not shown, and the app raises an exception:

Linux has no problem with colon in filename, but macos stiil has problem :-(
Under Windows is ok, because is imposible to add colon into filename

Hi, I can confirm that the issue with the dots has been fixed, but the problem with the colons is still there unfortunately. :-(

Maybe it is an issue of the Wand library, because if I force to use PILLOW all works fine. Besides if you try the first example at this page by replacing the output filename mona-lisa-{0}.png with mona:lisa-{0}.png, then the generated images have names lisa-1.png, lisa-2.png, etc. ; that is it discards the beginning part mona:.

EDIT: There is already a closed issue, and a possibile solution.

Many thanks for deep tests and looking for solution. I will correct code as was adviced

I think that this issue has been fixed in 5.0.7
