KDE 4.3.2 Qt. 4.5.2 latest git When trying to copy a CD to collection, I wanted to use the "Custom Format" naming scheme. When dragging a component (e.g. Composer) to the field, it crashes immediately, without starting Dr. Konqi. This is always reproducible. I run amarok with -d --nofork and get the following konsole output: amarok: BEGIN: void CollectionLocation::queryDone() amarok: we were about to copy something, lets proceed amarok: BEGIN: void CollectionLocation::startWorkflow(const Meta::TrackList&, bool) amarok: BEGIN: virtual void AudioCdCollectionLocation::showSourceDialog(const Meta::TrackList&, bool) amarok: END__: virtual void AudioCdCollectionLocation::showSourceDialog(const Meta::TrackList&, bool) - Took 0.14s amarok: END__: void CollectionLocation::startWorkflow(const Meta::TrackList&, bool) - Took 0.14s amarok: END__: void CollectionLocation::queryDone() - Took 0.14s amarok: BEGIN: void AudioCdCollectionLocation::onFormatSelected(int) amarok: BEGIN: virtual bool Meta::AudioCdAlbum::isCompilation() const amarok: END__: virtual bool Meta::AudioCdAlbum::isCompilation() const - Took 5.9e-05s amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Prelude & Fugue I In C (BWV 870)" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "1970" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "The Well-Tempered Clavier" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Classical" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "" amarok: END__: void AudioCdCollectionLocation::onFormatSelected(int) - Took 0.12s amarok: BEGIN: virtual bool Meta::AudioCdAlbum::isCompilation() const amarok: END__: virtual bool Meta::AudioCdAlbum::isCompilation() const - Took 0.00019s amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Prelude & Fugue I In C (BWV 870)" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "1970" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "The Well-Tempered Clavier" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Classical" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "" amarok: BEGIN: virtual bool Meta::AudioCdAlbum::isCompilation() const amarok: END__: virtual bool Meta::AudioCdAlbum::isCompilation() const - Took 0.00015s amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Johann Sebastian Bach" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Prelude & Fugue I In C (BWV 870)" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "1970" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "The Well-Tempered Clavier" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "Classical" amarok: I'm about to do Amarok::vfatPath( result ), this is result: "" ASSERT: "i >= 0 && i < size()" in file /usr/include/qt4/QtCore/qstring.h, line 685 Aborted (core dumped)
