The Error and the input filename

SUMMARY

For files with two doublequotes in filename, KDialog will only read in filename between the doublequotes.

STEPS TO REPRODUCE
1. Use KDialog to choose file (e.g. with Chromium or with Okular)
2. Select file with two doublequotes in filename (e.g. yechs_"test".txt)

OBSERVED RESULT
KDialog gives error The file "[current_path]/test" could not be found
(This is shown in the attached screenshot)

In the case that a file with name "test" exists, that file will be uploaded instead. 

EXPECTED RESULT
The full filename yechs_"test".txt being read in and the correct file be uploaded
