Comment 1 Peter Penz 2012-05-30 11:39:31 UTC 
Axel, the backtrace looks similar to your last report and might be again related to the tooltips and the Qt issue: https://bugreports.qt-project.org/browse/QTBUG-19363 Please try to turn off the tooltips and let us know whether this "fixes" the issue.

If turning off the tooltips does not help: Could you please provide the information whether this crash is reproducible by defined steps or whether it occurs only sometimes? We need a way to reproduce the crash otherwise it is impossible for us to fix it... Thanks!

Still waiting?

New DOLPHIN and KDE versions

DOLPHIN is not ftp capable-  I de-activated DOLHIN which seemto be a "spare version" of KONQUERER and run this file manager, instead.
Comment 11 Christoph Feck 2014-02-08 22:54:13 UTC 
I am using Dolphin for ftp sites every day, so your comment does not make sense.
