            Bug ID: 352957
           Summary: QT applications freeze when trying to Open File
           Product: kde
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: dan at farcas.me

Once in ~10 times the File Opener freezes when launching in various QT
applications(tested in Kate, Kwriter and SMplayer). To unfreeze the app I must
push the Escape button.

I can't get any good error output from this issue, I don't know if these are
helpful or not:

1) Got this error once, but in that instance the file opened
QXcbConnection: XCB error: 3 (BadWindow), sequence: 1427, resource id:
35692138, major code: 15 (QueryTree), minor code: 0

2) Got this error once, but the file opened as well. Created an empty smb.conf
file in /etc/samba but the issue persists.
KSambaShare: Could not find smb.conf!

A very similar marked as solved bug here:

Reproducible: Sometimes

Steps to Reproduce:
For example, open Kate or Kwriter
Press Ctrl + O and Escape a couple of times - basically open and close the file
dialog. The application will freeze at some point until escape is pressed.

Actual Results:  
The application freezes until Escape is pressed

Expected Results:  
The file dialog should open every time it's called
