Comment 1 Peter Penz 2011-06-17 19:49:44 UTC 
Thanks for the report. This is an issue in the corresponding metadata analyzer
that Dolphin uses to get the metadata of a file. Dolphin for KDE 4.7 won't
crash anymore in this case (see
http://ppenz.blogspot.com/2011/03/dont-crash-when-reading-metadata.html for
details).
