edb can not show save file dialog in ubuntu 21.10

[TheZ4ro]

when use edb in ubuntu 21.10 from dump windows, choose save to file, the dialog failed to display.

maybe this is a qt5 wayland bug?

• Are you using the default Ubuntu 21.10 install, with its default desktop environment?
• Is EDB installed from Ubuntu repositories or from other source?
• What exactly does "failed to display" mean? Do you get a message box, an error message in the terminal, or does EDB seem to ignore the command?

This doesn't look like a fix, more like a workaround. Native dialog is supposed to work fine too.

[TheZ4ro]

No, if you install ubuntu 21.10 default desktop, and edb dump window -> save to file will always hung even stop the whole destop. but the ubuntu 18.x works well.

[10110111]

I get a transparent window, rather than hung desktop, but yeah, Qt integration with Ubuntu desktop seems broken. A less intrusive "fix" may be to run EDB with XDG_CURRENT_DESKTOP=kde environment variable:

XDG_CURRENT_DESKTOP=kde edb

This will work even if you don't have any part of KDE installed, the effect will just be to avoid desktop integration.

@TheZ4ro，my computer system is ubuntu21.10 (gnome, 5.15.7-051507-generic),and it works well.

Its not working for me on latest kali rolling, it's transparent even with XDG_CURRENT_DESKTOP=kde env set.
