Description Fabian B. 2010-03-10 23:41:37 UTC 
Application: rekonq (0.3.98)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-16-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
open amarok or dolphin and select a *.flac (maybe too with other media types, but i cant test) now open rekonq and drag the *.flac from dolphin/amarok to the rekonq window. now drop it and it result in a crash. when you restart rekonq, it popup 2 (or more) windows and crash again. after another restart rekonq spawn in more and more windows but crash after all again. (maybe this is a other bug?) 

The crash can be reproduced every time.

 -- Backtrace:
Application: rekonq (rekonq), signal: Segmentation fault

Comment 1 Andrea Diamantini 2010-04-13 12:22:32 UTC 
It works here with rekonq from git (0.4.60). I guess your crash depends on the phonon backend trying to load your audio file.
Try loading rekonq from konsole as a music player:

$ rekonq audiofile.flac (.mp3, .wav and so on)

You'll see infos about the plugin and/or the backend trying to load your file.
It works here with GStreamer backend.

Btw, problems on crash reloading were fixed as last commit before 0.4 release :)
