Git commit 5fd1e7669b642de51391ce86994c1e44553b9bf0 by Halla Rempt, on behalf of Dmitry Kazakov.

[string-freeze exception] Fix loading TIFF images with embedded PSD data
In some cases the embedded PSD data may be loaded incorrectly into
Krita, in such cases we should let the user to choose, which form
he/she wants to load.
The patch breaks the string freeze, since it adds a dialog allowing
the user to choose between the two options.
