Bug ID: 52017
           Summary: Can't pick a folder in the folder picker (regression)
           Product: Wine
           Version: 6.18
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: shell32
          Assignee: [e-mail]
          Reporter: [e-mail]
                CC: [e-mail]
   Regression SHA1: 984f608c2885c80284ca8f35d6ad72d5193b3658
      Distribution: ArchLinux

How to reproduce:
1) Install Origin (doesn't install with plain wine, use wine-staging)
2) Select any game
3) Click on the gear icon in the game's card, select "locate"
4) In the opened file (folder?) picker, select any folder
On 6.18, I get an error saying that "The selection contains a non-folder
object". On 6.17, the folder gets picked just fine.
It is quite likely that this affects any application which requests to pick a
folder, but I'm not aware of any simple ones that do this unfortunately.
Bisect revealed the following results:
