Version:           4.5 (using KDE 4.5.4) 
OS:                MS Windows

In Dolphin on KDE for Windows, an address with the filename, for example, C:/somefile.txt will return the error "The file or folder C:/somefile.txt does not exist".

In Konqueror, this will work. Just as a note, once I press enter after typing in the address, a slash is being appended to the end of the address. I'm not sure if this is related or not.

In File Associations whilst adding an Application Preference (and browsing for a file), the error "'C:/Program' not found, please type a valid program name." is received. This is probably because quotes are not added and because the program has a space in it.

When quotes ARE added, the following error is received:
'C:/Program Files/SomeGroup/SomeProgram.exe' not found, please type a valid program name.

This occurs when the file does in fact exist.

Reproducible: Always

Steps to Reproduce:
(using Windows Vista, not sure about other versions; using KDE for Windows)

Go into Dolphin and enter an existing address with a filename at the end of it (that does exist). An error message should be returned stating the file or folder does not exist.

Go into System Settings > File Associations > Edit a file association > Add an Application Preference. Use browse to find an executable. Pressing OK should result in an error if there is a space in the name. Add quotes around the address and try again; this should result in an error stating that the address was not found.

Actual Results:  
For both Dolphin and the File Associations, error messages are returned stating that the address does not exist.

Expected Results:  
In both cases the address should be accepted. For File Associations, it should work all of the time and automatically add quotes around the address if necessary.
