--- Comment #1 from Frank Reininghaus <frank78ac@googlemail.com> ---
Thanks for the bug report. Dolphin itself does not generate previews - this is
done by an external thumbnailer process. Do you see the same problem if you
enable previews in other KDE applications, like in the file dialog of, e.g.,
KWrite?

No, the thumbnailer (which is an external process that is not part of Dolphin)
should be fixed such that it either creates a preview quickly and with low
memory usage, or skips the file if it finds that this is not possible.

I'm not familiar with the internals of the image thumbnailers, but I think that
access to a problematic file might be needed in order to investigate the
problem. Could you tell us how to get such a file?
