-- Information about the crash:
Over sftp connection operations may be slow and queued. While copying a large
file over sftp, I tried to create a folder on the same connection. The "New
Folder" dialog did not open immediately, so I pressed shortcut again. A minute
later two dialogs opened simultaneously. I closed one of them (the top-most,
i.e. which appeared last), started typing in the second/remaining one, and
Dolphin immediately crashed.

Sounds like those New Folder dialogs are not supposed to exist simultaneously.
In other words, no two in-flight dialogs should be created.

The crash can be reproduced sometimes.
