Hi, i found that disabling use of "qtengine" theme in GTK applications (from package "gtk-qt-engine") make flash-plugin works in konqueror -> just removed ".gtkrc-2.0" and ".gtk_qt_engine_rc" files in home directory. Distribution: sid Packages version: ii flashplugin-nonfree 9.0.115.0.1 ii gtk-qt-engine 1:0.8-1 ii libgtk2.0-0 2.12.3-2 ii konqueror-nsplugins 4:3.5.8.dfsg.1-6 ii kdelibs4c2a 4:3.5.8.dfsg.1-6 Andrea.
